Hopefully it doesn't take arm strength into consideration!
Just game on your computers guys. Toss the 500 bucks you'll spend on the system and games on Ram and a nice video card and you have a great gaming system. The games are always expanding and growing, and are light years ahead of consoles. Not to mention, many more control features, etc.
Granted some games (racing mainly) and sometimes sports I prefer on a console, but everything else I prefer on the computer. Bungie is rumored to be making a new game somewhat similar to myth (
www.playmyth.net)[myth's free if you want to try it let me know, when they were bought out by MS they gave it to the community], that will probably be ruined by going to Xbox because they can't match the complexity of a keyboard and mouse.
