Answer: Because they are stupid.
Next question!

Because they're not available in Germany.

I like the pricing for community games but quality is few and far between. Its also pretty hard to find them in the Marketplace.

I don't buy anything from XBLM due to a philosophical objection to their hotdogs & buns monetary system.

I picked other. Mostly because they are not on PSN but mostly because that's all I have. Got that?? Oh did I just break the system?? Also, why is Dtoid doing research for Microsoft??

I do buy Community Games

It's a time problem. There's so much coming out on all of the downloadable platforms that I don't have the desire to look up information about what's coming out, much less wade through it directly and guess.

Wow, CelicaCrazed.. Fucking spot on man! You deserve a heavy metal salute! \m/

Why IS Destructoid.com doing research for MacroShaft?

I'm afraid of buying a community game just to see it's a poorly converted flash game.

I don't care if a game is XBLA or Community, if I'm interested in it, then I'll check it out. I have no prejudice towards buying a community or an XBLA game, they're are simply both platforms to me and I will buy a game from either just as easily as the other.

Because they're not available in my country.

While there are decent titles there's also a lot of shit - fart machines, 'massagers', a calculator... who buys this shit? M$ should tighten up the quality controls, people can't take the XNA seriously with all this dross - a lot of which isn't actually games - coming out. I also think that the price point is too high at the moment, people know these games cost next to nothing to make, and since as you said they lack achievements, leaderboards, and high production values, they just cost too much. Finally, they aren't being promoted at all, and that's something the devs should take up with M$, a weekly appearance on the Spotlight channel or Inside Xbox would be good.

Dishwasher and Carneyvale show that great games can be made with XNA, but at the moment it's very hard to seperate the wheat from the massive amounts of chaff.

Sturgeon's Law, that's why.

I think there are a lot of crappy games on the Community channel. Sometimes it's poor production values, but sometimes the idea behind the game isn't appealing.

As some have mentioned, the time limited demos don't help things. It would be better to have demos more in line with the kind on XBLA or retail title demos.

With that said, I recently purchased my first community game. So it's not that I refuse to buy them, I just don't find many that hook me enough that I want to spend money on.

Severe lack of quality. People don't seem to understand that just because you CAN make a game doesn't mean that you SHOULD. There's a big difference between a developer and a great developer, and nowhere is that more evident than in the Community Games section of XBL.

Because they are not very good. I have played a lot of them (mostly 30 min trials) and there were only a few that I actually enjoyed.

mostly becuase of the other games coming out and the fact that a majority of the games are not really good. Its like the ipod app store, has some good games and apps but a majority of them is... well, you get the idea.

NO ACHIEVEMENTS MAKE KIT ANGRY

...but seriously, I don't usually buy them because they're not usually that good. I've only played one Community Game that I've found worth buying (Carnivale Showtime) thanks to Dtoid's review and I'll probably wait for the internet to bring any other good ones to my attention.

I could handle downloading XBLA trials every week to see if they're any good, but Community Games are updated too random for me to try all of them out and give them a chance.

Also, the trial time is too short. I need at least an hour of straight gameplay to decide if Fireplace is worth buying or not.

I've bought two.

Poor quality games that range from mildly amusing to downright useless keeps me from paying for a community game. However, release something of quality that's creative and fun and I'm on it like a cardigan on a librarian.

Quality is my reason. Usually a 500 point XBOX Live game is better than the most expensive community game.

There is only maybe 3 or 4 decent, not great, not good, just decent titles on it.

Community Games got me excited because I hoped to see creative output from otherwise cash strapped developers who couldn't afford to invest so much into a game to make it a full XBLA release.

Unfortunately, whenever I load up the Community section of the marketplace, I see useless and silly garbage, like the Massage program or the clock and fireplace. I want to compare it to the iPhone apps mess but at least those aren't specified as games. To go to the Community Games section and see a program that will let me tell time with a giant cat on screen with clocks in it's eyes? And having to pay 200 moon bucks for the privilege? Give me a break.

There are a handful of decent gems in there, but the majority of it is harmed by laziness, half-assed concepts, and low creativity. I hardly open the Community Games tab anymore. It's like staring at a tab full of Coffeetime Crosswords and no end in sight.

Well not only do I hate buying games from XBL as the process of buying points is stupid and the conversion rates don't seem to be quite right. As for community games I have no idea whether they're good or not, they don't look appealing and they're overpriced like any other XBL game.

I don't buy community games because Micro$oft charges 99 Dollars for a 20 gig laptop hard drive. This is probably because they're having to pay the hardware manufacturers to keep making them. since... ya know, the smallest size hard drive you can get easily right now is 160 gig.
