I'm actually tempted to get a Wii. Granted, I also want to get a PS3 for MLB 2008: The Show, as baseball is my primary addiction. The thing is, I bought an XBOX when it first came out and have almost never used it. I got the MegaMan history collection, but I like playing it more in emulators. Same for the Street Fighter Anniversary Collection on X-Box. Also, Halo isn't that fun to me.
Ah well. Maybe I'm just getting old and liking the old school games too much. :p
