i got 2 words for ya: GAME FLY (gamefly.com). it's like $20 a month to have out 2 games as long as you want. and if your bf is like my husband, he'll try stuff out and hate it. 360 games can be expensive ($30-60), and selling them back to a store like EB you WILL noT get close to what you paid.
i recommend: Gears of War!! it's got bad language, but it's a super great game, good graphics. (i hate it, but my son and husband love it.)
i also recommend: Guitar Hero...except my husband wouldn't let anyone else play...
you can also get a 2nd guitar and jam together!!
true story!!... if you move the 360 with a disk in it that it
can ruin the disk. we just had to replace our copy of GOW b/c my husband decided to move the 360 from the bedroom back into the living room.
wireless controllers are the key.
i'm sorry this has nothing to do with your sale, but maybe i can save you some money elsewhere
