Looking at Zelda for Wii U , it just looks so beautiful and to me beyond what the PS3 and 360 can do. I also think that a game like Smash Bros Wii U wouldn't run on the PS3 and 360 without framerate issues.
I remember people on here saying that the Wii U has more RAM than the PS3 and 360 but its clocked much slower that it doesn't really help it as much, but was that really true now with the games we see coming out for the Wii U?
Well the best on Ps3/360 is still pretty amazing.
I don't think GTA V get beaten by Zelda U.
I don't see anything special about Smash, there are many 60FPS fighting games on Ps3/360 looking equally as good.
Of course, different people prefer different artstyle.
Its also very hard to compare the best on Ps3/360 to the best on WiiU.
How would you compare Uncharted 3, Beyond:Two Souls, GodOfWar: Ascension, Killzone3 and GTA V to MarioKart8, Zelda U and Xenoblade?
Completely different looking games.
But WiiU is stronger than Ps3 and Xbox360.
Especially the GPGPU stuff. Compute commands allow developers to pull of more stuff while maintaining a high framerate.
