Trine, is not incredible also, very good, it uses some good textures, and models, and shaders, but it is still a little game.It don't have incredible level design or gameplay, or character design like in God of War 3 ! You can't compare what is not comparable ! It's more some sort of very refined visually mini game.
But this is not really the point. Trine is a small game, yes. But it looks consistently beautiful. I thought this discussion is about graphic style, not about the size of a game, the amount of character animation or anything else.
And this is exactly what I meant: Small teams (hobby or indie developers) can create nice and consistent art. They can create something similar to big productions, just smaller.
