Actually before I continue we all do. Ok that was a bit harsh, 99.9% of us do. Sure we save the world, stop evil's plan, and manage to get our characters home. However most of us suck.
Firstly, I have completed alot of RPGs and everytime I do something wrong. Its not cheating, its not having to respawn because my level is too low. No its the opposite. I grind my levels.
Now most the time this is fine no problem, it makes sense. However how many of you (and I definitely do it), grind your levels whilst the threat of evil looms overhead. I'm currently playing Super Paper Mario, and the whole universe is at peril from the get go. There is no time to waste! So I go down to the extra dungeon and grind my levels. I could be there for weeks, not caring about the universe, but just about my characters' level.
That black stuff, that isn't good, but who cares I want to be stronger than anything else in this universe....the quickly disappearing one that is.
Who hasn't played an RPG where the main boss has captured the princess/girl/king/boy and is going to use their power to unlease hell upon the land, and decided actually I'm not strong enough give me 2 hours and I'll come and fight you. If I was an RPG boss I'll have defeated good once and for all within that amount of time.
Even Fallout, which had a time limit for the game, I did this with. Not with the main objective (only because you lose if you don't complete it within the time limit). I did that, but then I grinded my levels when I should have been running to the rescue.
So next time the world/girl/city needs saving, dont wait and grind your levels, play the game properly and rush in. The world needs you.
