WHy are you in a computer thread, with $400, and asking computer people what to buy, then say you don't want computer parts. ***slap*** what's wrog with you!
Anywho if you MUST spend it, buy something that you will use for awhile, not a game, because in a few weeks you'll have beaten it and be done with it. Get something such as a car, get somethign BIG and FUN. There's cheap fun cars out there, might as well get somethig you can actually use...
Oh and buy that one guy his video card...
