My partner and I have a Wii and the Wii fit board which was bought after a long spell of bad health with the idea to get some exercise whilst having a bit of fun. Soon became boring and I must say has not been used for some time. Games prices are pretty steep when compared to my gaming platform of choice, the PC. I would love to combine a FPS with full body movement. Ducking and diving,peeking from behind cover for that sniper head-shot. No doubt it will come, hopefully in my lifetime.
gengiscant - I played something like that in an arcade a few years back, I think it was the Trocadero. You had to dodge around on some steps that detected your weight moving around - a bit like those dancing arcade games - while shooting at the enemies. It was utterly exhausting.
360 20GB PSOne Grandstand Video Sports Centre (1980 model)
The 360 hasn't seen much actual gaming usage in it's two and a half years, mainly because I don't really like playing FPS games with a gamepad. Mostly used for messing about with GTA Liberty City, and as a DVD player. My now elderly PC gets used for gaming far more than the 360. The other two consoles are in storage.
Have also owned a Playstation, a Dreamcast, and a PS2, but they all got traded in.
If Microsoft had given the 360 mouse and keyboard support, it would have been ideal for me.
