I haven't played my Wii since I got my Xbox 360 about 5 weeks ago. Probably only played it on average about once every 2 weeks before that. The last game I can recall actually being entertaining was Metroid: Another M, and I played through it the week it came out. Usually the Wii is used only by my kids, or by me if I want to play an old Neo-Geo fighter on the emulator, or watch a DivX movie that I'm too lazy to burn to disc for my DVD player.
In all honestly I'm sickened by the Wii every time I see it being played by the kids now, it just looks like total crap compared to the Xbox, and it is really hard to imagine that they are from the same generation, and even more outrageous is the fact that the Xbox is older than the Wii. I had never played an Xbox 360 or PS3 until 5 weeks ago, so I had no idea how huge the difference was. The Wii is more or less just a Gamecube with gimmicky controllers :-[
