I'm not going to deny the frame rate issue but the whole game engine is far more ambitious with proper collision detection, far more realistic graphics, more happening in the game world and a decent physics engine. It's hugely impressive. Xenoblade doesn't strive at all for realism, its single goal seems to be impressive graphics but with terrible pop-in and a simplistic engine. Reminding me of Monster Hunter somewhat.

The only similar open world game on wii u is watch dogs and not only does that fail to surpass 360 and PS3 graphics but it does so with lower frame rates, horrible slow loading and what can only be described as disc drive destroying never stopping disc access because of the lack of hard drive.
