In all honesty, after watching all three press briefs, I think that Nintendo had the best one. Why? Because we have seen all the crap on the PS3 and 360 dozens and dozens and dozens of times before. Yes, MGS4, Halo 3, GT4, Gears of War, Mass Effect, FF13, and all the dozens of other games by them look nice, good for them. I, for one, am getting kinda tired about the best pixels per inch, and soft shadows and all that other technobabble **** that Sony and MS are spewing. After all, good graphics do not make a good game.
But Nintendo had something those didn't... I don't quite know what, maybe it was heart, maybe it was balls, maybe it was insanity. I don't know, but the Wii looks to truly be next gen. Not only in terms of control, but terms of art. Now, art and graphics are two different things. The graphics, while they look nice, look stale and plastic. What Nintendo can do here with the Wii, since the technology there isn't too far off from the current gen, is push the art of the games further than ever before. I have watched the thrity-odd second Mario Galaxy playdemo over and over and over now, because I still can't get over the art direction there. It looks friggin great!
