The simple math of review scores photo

Editor's Note: We're not just a (rad) news site -- we also publish opinions/editorials from our community & employees like this one, though be aware that it may not jive with the opinions of Destructoid as a whole, or how our moms raised us. Want to post your own article in response? Publish it now on our community blogs.

A couple months ago, I would have never considered writing a feature about how review scores work. First off, I rarely review games for this site, and, secondly -- and most importantly -- I have no interest in getting involved in the never-ending, exhaustingly fruitless argument over why certain games are scored a certain way.

But over the holiday break, something changed. As I started reading the comments on some of Destructoid’s more recent reviews -- specifically Assassin’s Creed II and VVVVVV -- I felt the need to throw in my two cents.

You see, there is one particular issue that is bothering me that I think a lot people genuinely may not understand. Of course, this has nothing to do with people’s opinions on how a videogame is scored. If you love a game and it gets a low score, it makes sense to respectfully disagree with the review. This feature is not about telling anyone that they are wrong for feeling the way they do.

No, this feature involves comparing one review to another -- a misconception that is starting to infect the comments of almost every review that is posted on this site.

Hit the jump for a simple solution to solve everyone’s review score woes. Let’s all hold hands and read together.

Honestly, I can keep this rather short:

Review scores are not meant to be compared to each other.

Simple as that.

If a game on this Web site gets a 9.0 and another gets a 7.0, it doesn’t mean the game that gets a 9.0 is altogether better than the game that was scored a 7.0.

Before rushing to the comments and letting me know what I am saying makes no sense, let’s go over how a numerical score is calculated in a review to begin with.

Each review and its respective numerical score (between 1 and 10) is based on the quality of that particular game. If a game gets a 5.0, it is completely average. More specifically (and this is super important!), giving a game a 5.0 means that the game being reviewed could, technically, be about five points better if certain things were improved. In more mathematical terms, this means the game is living up to 50% of its potential.

Think about a game you really love or hate. Now, mathematically, think about how much better that game could be. If it couldn’t be better in any obvious way, well, that game should get a 10 (or, at the very least, close to one). If the game you are thinking of could be significantly improved, think about how much and score it accordingly. Could it be three points better? Six points? In relation to what it is setting out to accomplish, how much of the game is successful? 30%? 85%? 100%? Boom. There’s your score.

But let’s move on from that -- we could debate what a “5.0” really means for days. That’s not what this article is really about.

The point of this article is to not dissect review scores; it’s to dissuade everyone to not compare them with each other. It may sound simple and obvious, but it is unbelievably important.

With a lot of reviews, people look at a numerical score and surprisingly refuse to think about what that score actually means. It’s just “OMG [GAME A] GOT AN 8.0 AND [GAME B] GOT A 9.0! DESTRUCTOID THINKS [GAME B] IS BETTER! FAIL!”

Let’s use the “5.0” example once more. If a game gets this average review, the score only applies to that game. Meaning: if the inevitable Assassin’s Creed III gets a 5.0, it means that particular game could easily improve things to make it five points better (be it graphics, gameplay, etc.).

Conversely, if another game -- an indie game, for example -- gets a high 9.0, that doesn’t necessarily mean it is a better game than Assassin’s Creed III. It doesn’t mean that at all, actually! All it means is the indie game is so good it could only make enough improvements to score it one point higher.

In no way does it mean the indie game is exactly four points better than Assassin’s Creed III (whatever that would even mean).

Review scores are meant to reflect the quality of a particular game. They are not meant to be compared to each other in any way. If a game gets a 7.0, that game got a 7.0. If another game gets a 2.0, that game was scored a 2.0. In a normal review world, a game that gets a 6.0 could or could not be “better” than a game that gets an 8.0. Unless the reviewer specifically states, “[Game A] is better than [Game B],” there is no way to tell which game is better based on the review scores alone. Again, each review exists in its own individual world and should be read and understood accordingly.

Personally, if I were to review Dead Rising for the Xbox 360, I would probably give it around a 6.0, due to some serious problems I had with the game’s controls and certain design choices. The game could have easily been four points better if Capcom changed some key things about it. Easily four points better. On the other hand, I would (and did!) give Planet Puzzle League for the Nintendo DS a 9.5, as it is near-perfect in the kind of game it sets out to be. It could have only been, at the most, a half a point higher with some small, merely cosmetic (*cough* friend code *cough*), changes.

But ... if someone were to ask me what game I like better, I would easily choose Dead Rising. I love that game, despite some of the problems I have with it.

Let’s use a popular ongoing series as another great example of all this.

The Madden series.

Every year a new game in the Madden series comes out that is almost identical to the one before it. Say in 1995, Madden ’95 was ranked a 9.0 for being one of the greatest football videogames ever made.

Obviously over the years the Madden games have improved in various ways -- more features, better graphics, improved simulation. Between 1995 and now -- if reviews were meant to be compared -- how could you do better than a 9.0 year after year after year? Answer: You can’t!

That’s why each game is judged on its own quality, with no intentions that its review will be compared to another. If one Madden gets a 9.0 and another gets a 7.5, that doesn’t mean the 9.0 iteration is better. It only means that the 9.0 game lives up to 90% of its potential, as opposed to its colleague’s 75%.

If a chef prepared a plate of brussel sprouts that 9 out of 10 brussel sprout experts adored and another plate of chocolate cupcakes that only 5 out of 10 dessert experts loved, you can bet your ass I will still be asking for more of those average chocolate cupcakes, while ignoring the plate of almost perfectly prepared vegetables. Why? BECAUSE A 5.0 CUPCAKE WILL ALWAYS BE BETTER THAN A 9.0 BRUSSEL SPROUT!

Okay, I admit that was the worst analogy of all time, but hopefully you get an idea of the point I am trying to get across: Review scores should never, ever be compared.

In no way am I calling anyone out for not agreeing with the reviews we do here. Like I mentioned before, everyone is entitled to their opinion, and we respect and adore the Destructoid community more than you will ever know.

Just remember this little insignificant feature the next time you want to scream “Destructoid thinks this game is better than that game! Confirmed!”

What you are saying really doesn’t make any sense.

okay, i just wanted to get in there with the juvenile '4.5' joke before anybody else. I have actually read the post this time :) and i wholeheartedly agree. People take the score/percentage of a game too literally and this is a very good explanation of how it works.

Also, at the end of the day a score is a reviewers opinion. im sure we all have a game that we really enjoy which got slated by critics

I understand why you post this but I don't think you'll get the point across. People look at scores for a game and see what other sites think. Depending upon which site's review they like better they'll comment on the other site about the score it was given on their favorite site.

Not all reviewers are the same and some are more critical on games than others. Which is why I think overall people should look up multiple reviews so they get different viewpoints on it. As a whole that should be what you base your decision on opposed to just one person's opinion of it.

I think that part of the reason why people compare review scores is because if they have to decide between game A and game B if game A has a higher score, they are more likely to buy it than game B. I think this put a new perspective on how I will view the scores though. I previously thought that a 5 was an average, middle of the road game (in my mind: Timeshift), and the rating was based off of that. Interesting to consider an internal comparison instead of a comparison against all other games...

Having 5 be "average" makes no sense. When scoring or grading things in the United States, it's almost always referenced to the scales in school. 7 (70) is considered average. 50% is porous.

Awesome post Mr C, but I fear it will fall onto deaf ears. The type of person who gets upset about the number a stranger has personally assigned a game overall, really aren't interested in lateral thinking and sleeping with members of the opposite sex. They're too uptight about numbers and figures, the short hand. They can't be arsed to take the time and read a review properly, but they sure do like to make others read their protests. Arrogant bastards. Their heads get so swollen, I'm surprised they can see at all, which explains a lot. They're blinded by their own stupidity!

Oh yeah, I forgot to add. A score usually is a score based on a 1-10 scale on different aspects of the game resulting in the final score (Not necessarily this site) (This is kinda obvious facts tbh, not sure why I even type this.)
Let's say my score is devided by 1. Graphics. 2. Gameplay.
I give game (A) a 10 in graphics and a 1 in gameplay it will average a 5. Vice versa with game (B) (10 in gameplay and 1 in graphics) and it will average 5 aswell.
I would say that the game with the better gameplay is better, but you can't really compare the two. So yeah, kinda pointless post I guess.

I can see your point. But a universal scoring system like the one that exists (more or less) today tends to encourage, even demand comparison.
More evidence that the numering rating system is crap?

What Sonvar said. No one should rely on any single review to get the whole picture. For something as expensive as a $60 purchase, multiple viewpoints are required.

Good points, however, I think it misses out on what the reader generally expects from a review. Readers expect scores to be a standard, so a 8.0 comes off as being higher recommended than a 8.0 (this feeling is helped by the fact that your site's revies have an explanation of what scores translates to at the end of reviews). Quite frankly, I second the opinion of whoever aaid this article should be linked at the top of each review, because otherwise, I don't think most readers would have assumed this was the case otherwise.

I get the problem with reviews, the only real quantifiable stats of a game (gameplay responsiveness, graphics, framerates, length) would constitute a fairly boring review, but everything else is subjective. I do understand as well how an 8.0 could be better than a 9.0 (perhaps the game is so great, you don't mind slightly wonky controls etc, but we marked it off anyway). And I can see how indie games or casual games could be graded on a different scale than traditional games (indie 8.0 does not equal traditional 8.0 etc), but if you are going to make the review scores so intangible, you are probably better off leaving them out completely.

So, Chad, is this the official game scoring policy of Destructiod? If so, perhaps it should have been posted soon and in an official capacity.

Unfortunately, when something is posted as an 'editorial,' like your article is, that lies in direct opposition to the claim your article makes.

Seriously!? I hear this argument a lot but let me just say. If you don't see how on a scale of 1-10 5, the number directly between the two, being the middle makes more sense than having 7 you need help. Yes it's different in schools but no one said we were supposed to be grading like in schools.

I get your point and all but it still comes down to the straight score for me. I mean this whole "potential of what the game could be" thing makes sense but that's not how reviews work. I mean every game should have the potential to be a 10 so in the end if a game gets a 9 and another game gets a 2. The 9 should be all that much better because they are both on the "100% potential scale". I mean, what if I were to say I was going to make a game that had a stick figure that could move to the left and right and that's it. It's only potential would be that it will have a guy that moves left and right. So as long as it does that you think the game should get a perfect 10? It is living up to all its potential after all. You even said yourself:
"The point of this article is to not dissect review scores"

So keep it simple then. a 9 is better than a 5. always.

p.s. the cake/ brussel sprout analogy only works if your comparing two different foods (games)to each other(which is a little stupid I admit). But if you were to see a cake that had 9/10 satisfied customers and a cake that had 5/10... tell me what one you would pick.

Finally someone official says it. It won't shut people up (even if you agree with this post exactly what a score means is still up for eternal debate) but this does make sense of the comparison debacle.

At least it's made a believer out of me. I always thought while scores should be compared they should be able to be compared. It think this argument overshadows mine though. Congrats.

Wouldn't the world be a lot better if we just got away with review scores and just did a thumbs up thumbs down system? Then people would actually have to READ the reviews before they threw a hissy fit. A lot of people just see the score that a particular game gets and don't bother to read the reasons why it gets said score. Seriously, why do we need this totally arbitrary number attached to our games?

I point to the game Ar Tonelico II for example. I despise that game, however certain parts of it are really very good. The graphics are nice and niche and colorful, the music is...eh...I guess, but the gameplay was a steaming pile of donkey poo. It was so bad that I scored the game a 4/10 because a certain other website only lets you review in numerical score, where as I normally do a buy/rent/skip format. Now granted 3 of the 4 major review points of the game were fine (graphics, sound, control) but the gameplay was such a big issue that when pressed for a score, I honestly gave it what I thought it deserved. Of course it doesn't stop the fan boys from flaming me on the message boards. Not that I really care what people who like playing a game where girls leveling up involves taking a bath together.

@Woverine,
I get what you are saying, but the point of the analogy was to prove two different videogames are not the same. Meaning: comparing two cupcakes to each other is not accurate. Puzzle games (cupcakes) should be reviewed differently than an epic RPG (brussel sprouts). True, the meaning of the 1-10 scale stays the same (1 is terrible, 10 is amazing), but if the puzzle game has much "simpler" components than the huge RPG, does that mean it can't get a 10? If the RPG has better graphics, a better story, and better technology, that doesn't automatically make it better than the puzzle game.

If the puzzle game is a perfect puzzle game, as simple as it is, it still warrants a high score.

If the RPG is great, but far from perfect, it should earn an appropriate score (7,8). That doesn't mean the RPG is a worse game, though.

Make sense? :)

I guess I am just trying to get people to not see two COMPLETLY different games, compare their scores, and assume which one is "better" based on scores alone. It doesn't make any sense!

Man, this is not "simple" at all. Haha. :)

Exceedingly well done explanation of what is often in the back of my mind when reading reviews of simple games, and genres I simply do not like (Fight games, MMOs, team sports, games with glowing energy weapons, the list continues to grow).

There also seems to be growing evidence for me that there is little actual reward for making excellent games.

An excellent game once experienced seems to really invalidate the rest of the product line available on the platform.

I feel hesitant to suggest we are all rational consumers and that 'Perfect information' (HD video, large game screens, demos, accurate reviews and marketing) available to all people who sought to play only excellent games would really decrease game sales.

In my case however, it seems the more I know the less I want to buy, because I consistently feel developers do not even attempt to deliver quality that stresses the capacity of the platform.

A simple example would be infinity ward gimping their game to 600p for both platforms.

This is one of the reasons I always read the "Super Reviews" at GamesRadar. They spell out, at the end of the review, whether the game in question is better or worse than other games in the same genre. Very helpful.

This is just another reason why review scores only work to hurt video games. You can't rank two totally different games with numerical scores based on their quality and not expect people to compare the two. As a reviewer, it's your job to provide the proper context your readers need to understand where the game succeeds in comparison to similar game experiences. Sites requiring their reviewers to slap on a score at the end demean the process and their readers.

As for your analyzing the percentage of a game's success or lack thereof to determine its score, I think that's just ridiculous. How can you tell people not to compare game scores to one another, then ask them to determine a numerical percentage of how much more successful it can be?

@TheDirtyHobo,
I think our scoring system is in line with this article.

I am not saying we score our games wrong at all, or that we should change the way we evaluate individual games. If anything, I think we are more fair and realistic than most gaming sites out there! I just don't think people should compare all of our scores next to each other to determine which games are better than others.

That's what I was trying to say, at least. :)

I respect what you are saying, though. There may be some review inconsistencies every once and a while. That's hard to avoid. :)

Well said. I think it should be a mandatory read before commenting - we could avoid a lot of idiotic comments.

The amount-of-potential perspective also makes a lot more sense than most others I've heard around here. I wish scores could be ditched altogether, but since they're here to stay I just wish more sites would use the entire damned scale.
