There are, quite literally, no good 'real' games for the Wii as a console. It's sad that the damned thing has been out for two years and the game it came with, Wii Sports, is still in it's top ten games. The Wii has literally been riding on gimmicks, and when you strip those away all you have left is a naked and broken Game Cube. The only real redeeming quality of the Wii is the virtual console features, which allows you to pay for 'retro' games you could download for free on your computer.
Even when Nintendo gets a hold of a decent title, like Okami, it manages to screw things up. Okami on the Wii, while in theory sounds good, was poorly executed with ridiculous and confusing controls. Trying to draw a circle, nay, a straight LINE is almost impossible with the Wii'mote. It's almost like having Parkinson's disease. I loved Okami, but hated it on the Wii.
