Bro...not to be picky or anything, but SPELLING. Learn it.
OT: Because most of its games use the motion crontrols and a gimmick, the other consoles don't have to worry about their games being rendered s*** because of the controls, and they're graphically better and have better exclusives for serious gamers (by which I mean gamers who prefer serious games). There are games for the Wii that do try to take advantage of motion controls, but many of these end up poorly for trying. Lastly, often the controls amount to shake the controller around to perform X move as opposed to actually moving the controller in that way, which is a bit stupid. A lot stupid, in fact.
Basically you can get more consistent good content that doesn't have to bend over backwards to accomodate its own console by not choosing the Wii. That said...I nearly bought one for Monster Hunter. But I didn't, I stood my ground. CAPCOOOOOMMMMMMM!!!!!
