ive always loved batman and now there is a large free roam batman game its kinda killing me i cant pay for it yet cause ive put of buying tickets to NZ for too long so that will be my pay abd after that i have to do xmas shopping ok so i have

bf3
red dead
forza 3 [the dlc disk is missing]
gta episodes of liberty city [some where]
and black ops but that's scratched to hell and doesn't load nuke town

im in australia is that enough to trade the game for should i try EB games or game traders? [for people in the states a new game is about $100-$120 not $60]
