after playing mh3 demo i must say i´m not impressed... like.. at all. The graphics are nice but not outstanding. Very bad textures on the mobs and monsters. The gameplay is obviously the same as before. I played the MH on Wii and it feels exactly the same. I´m glad i tried the demo. I can see why people like it but in the end, it´s just not for me.
I played the 3DS demo and even that feels noticeably smoother than Tri. I'd expect it to be even better with the Wii U version.
