I agree with RAB and KDR on this. I think games like Wind Waker, Mario, etc are excellent in terms of gameplay and style, and the graphics are great, but in some ways I really think they could be better. I'm not saying they should be "realistic" or anything, but perhaps more detail could be put into them, like KDR said. The characters in Wind Waker had awesome animations and whatnot, but sometimes they just seemed too...simple, I suppose. I know that was the style Nintendo was going for, but they could have still kept the "cartoony" style while at the same time adding more detail, such as sharper textures. In real cartoons, (at least the ones I've seen) even most Disney movies, the backgrounds are very detailed and the characters--though somewhat simplistic in design--have a lot of detail too (for Wind Waker, I always imagined it to be almost like the art style in Emperor's New Grove, only not as exaggerated). Not too sure if that makes a lot of sense, but yeah...
Basically, what I'm saying is that some parts (not all of it) of Wind Waker and other recent Nintendo games seem to be lacking a lot of detail in environments and characters. In Sunshine, I really don't have any gripes about the graphics; it's a platformer, so the lack of detail doesn't distract gamers (I played SMS just a couple hours ago--still think it's an awesome game). With Wind Waker, however, there is a lot less jumping and more walking/sailing around and looking at things. In my opinion, the designers put the most effort into Ouset Island, what with moving grass, lots of characters and houses, etc. But on Windfall, there isn't any slashable grass at all (you can check for yourself), just dull clumps of bushes that don't move unless you swing your sword at them. Even then, you can't cut down the bushes like the ones at Outset and some of the smaller islands in the game. I know this isn't a very big part of the game (not by far, lol), but when you just want to wander around the town it's somewhat disappointing when you bump into plantlife and it doesn't even wobble, or you just walk right through the graphics.
Anyway, to get this over with, my point is that in some of Nintendo's games it seems like they leave out detail that could have otherwise been easily added. I'd post more of what I mean exactly, but I have to go. And if none of this makes sense, I don't know what to say.
