when i trade lots in i price match cex with gamestation, i printed out the offline version of fifa and gave them that and explained, but i imagine they would of excepted the other, as for devaluating games, its gonna kill the preowned multiplayer game market,
not only to you pay more if preowned, you get less for tradeins. i personally dont like it. i feel once a game is bought, its bought, end of. theyve made there millions of pounds in 1st hand buys, so why the extra code. it will probably be one step too far
if cod charge for an online pass as its 45 anyway so it will probably boost the preowned pass u ptoo.
