You should take another look at last gen games. Im replaying Metal gear rising right now,platinums last big ps360 game and graphically, it is getting blown out of the water.
Not only is their a LOOOOOOOT more simultaneous enemies in tw101, including big enemies, but aside from the ant sized ones their polycounts and textures are putting rising to shame, in comparison, rising looks very, very blocky and blurry.... and very very tiny and claustrophobic.
And also, ps360 games dont use polygons to write the speed limits on the ground, and for writing on signs. In no way shape or form could tw101 be brought to 360 in tact, not gameplay, not enemy count, not art style, especially not art style, tw101 uses polygons for detail work the entire 360/ps3 generation used normal maps to hide, and games designed like tw101, large scale zoomed out view, didnt ever come anywhere near to remotely close to tw101's fidelity when zoomed in like tw101 constantly does.
I am not as knowledgable as ou when it comes to tech. I just wish there were more games available on Wii U that has a more realistic artstyle so these differences can be shown. I am not saying it is right but people do disregard games from being technical achievments because of artstyle and we know nintendo usually goes with a more toon look and style to their games and I am not saying their is anything wrong with that. I am pumped to see what Zelda U does visually but it might be a new METROID that show what Wii U can really do or whatever it is Retro games is working on now.
