Wii Boxing
Ok, I just spent the last hour kicking some ass on Wii Boxing. I love that game. I actually bought a Wii just for the Boxing.
But I really wish Nintendo would one up the boxing game with a full game dedicated to boxing. They could spend more time on it to make it more realistic and sell actual gloves with it (not like the wii-mote cozy style gloves currently on the market but gloves with real wii sensors). I would buy that in a heartbeat.
