It's pretty fun, I like it a lot. I don't own a PS3 yet, but I like the wii at least as much as my 360. I just wish some of the developers would get with it.
That is one issue with the wii is the lack of developers making games for it. Though one major advantage to the wii is that it can play most gamecube games.
Also, have you played the Resident Evil 4 version for the wii, I have been wanting to know how that turned out.
There's plenty of games out for the wii, it's just a lot of them are shovel ware, but its gotten more good games then the PS3 and if you look at the 360's first year or so, it's pretty comparable.
RE4: wii edition is nice, if you combined the PS2 and GCN versions and added wii controls, you have this game. Better visuals with awesome control and all the bonus content.
