i picked this up at microcenter at 6 in the morning. i didn't go for this but i noticed it and got it for 30 bucks which is pretty good. i don't particularly like this game, but for this price i had to. anyways, the problem is that i tempted to play it since i heard it's so good, but the game i really want is mgs3. so should i open and play it for a while and trade/sell OR trade/sell right off the bat so i can get mgs3?
