Xbox 360 + Kinect FTW. It's nice how the 360 is completely wireless, you dont need to hold remotes or, gadget's or anything to play, unlike the Wii and PS3, Don't get me wrong there nice and all, but 360 is just epicly awesome, Not to mention all the modding you can do, plus all the JTag modding. ( If you don't know what Jtag is on 360, google ftw. ) Were getting a 360 + Kinect for X-Mas, so it's gonna be pimp.
Also, about the online thing, they got a deal going on right now, 100$ For 4 Accounts with 1 year membership. It's a great deal too!
