As far as I have read, no one has played the game on Wii yet to give impressions about it.
These screens do not look bad at all, and with the Wii remote it could be a fun title. However, I'm really feeling the graphical gut-punch with this game. Why can't the hardware be more powerful? I would pay $300 for a Wii, easy, so long as it still came with two Wii Remotes and Two Chucks (Wii Sports would be nice too). I suppose I have to live with it. Mario and Metroid looked very good at E3. Although Metroid's environments and character models seemed only marginally improved, the draw distance in the outdoor areas was huge, and each room was twice as big as those in MP2 (which was a cramped game altogether).
I've shrugged off fanboyism long ago (I'm Nintendo centric only to save money), so buying another system to get the graphics goods isn't out of the question for me. And, I guess, Call of Duty isn't exactly a huge title for me personally to get excited about (plus the 360/PS3 screens in EGM looked good, but not great.) Still, I'm praying for a Wii game that really blows off our socks - if Mario's the one to do it, that's fine, but I'm hoping for more.
