so my parents were going to get my brother a 360 for xmas, but we weren't able to get one in time (of course). anyways, we finally were able to order one today. should arrive in about a week. right now he has perfect dark and cod 2, but he's going to try to return them and just rent stuff... we have a gamefly 2 game subscription. so the question is, are there games that are worth playing, but moreso just for a rental, vs games that are worth owning? i would imagine sports games are about the only ones i'd want long term (with the occasional halo or oblivion, which he will certainly buy). but the current sports games are so crippled and worthless, plus they're not really his favorite in general. also, what are the upcoming games that people are really looking forward to?
