I'm curious what you guys have to say about this. Are there any games you consider perfect? Can a game even be perfect?
My example of a perfect game is always Portal 1. Portal 2 has more going on, but in 1 there just isn't anything to shave off. From start to end, there is nothing I'd change about the game. It's short, infinitely replayable, great pacing. I like Portal 2 a lot in concept, in concept it should be a perfect sequel, but it just doesn't keep the extreme tightness of the original game.
You also get to wade through eye cancer inducing lava with copypasted dragon butts for minutes and fight a gimmicky platforming boss that can just randomly kill you if it feels like it.
They just didn't finish the game properly. It doesn't take away from what that game means to me and to the medium as whole, but it is undoubtedly a flawed product.
Oh yeah.. I always forget about the dragon butts..
