At least in most cases they shouldn't.
 
Some games have a very strong engine and can come up with the most lifelike and realistic cutscenes ingame like on demand.
Look at Mass Effect, there's a lot of choices in that game and none will have you question the visual flair you experience.
It totally fits too, that's half the idea, it's one big streaming story.
 
So why do you punks even get the guts to complain about other games?
For most of you gaming started way back when you were looking at a couple of pixels.
Hell you were jumping your way through Mario World, sidescrolling in Ganbare Goemon or playing insanely long RPG's.
Why do you feel entitled to lifelike graphics? Does the gameplay not satisfy you anymore?
Do graphics really matter if you're into a game?
 
I don't think there's much ways to prove yourself to be a real gamer...
But if you hate on games because they're on the Wii, or of an older generation or such, you need to shut up and keep your opinion to yourself.
Just because you dislike the graphic quality/style/whatever does NOT make it a bad game.
Maybe for you it does, but seriously, we spend years playing previous generations and now it suddenly hurts your eyes? Boo,fucking, hoo.
 
Go make a topic about it, go hate on me.
I'll be playing on my gamecube meanwhile, you know, doing what a gamer should do.
