most likely wont be retroactive. i would be very very pleasantly surprised if it was. where would the info of u completing some of this stuff be saved? and if it were saved somewhere, why not release the trophies in the first place?
so is this official now or is it still just a rumor. someone was saying it might be a trick cuz it was the same as the xbox trophies besides that platinum one (which i think means get all the other trophies). i guess ill look over all three lists (xbox, original ps3, and this ps3) and see whats similar/different.
because i cant edit my last post for whatever reason ill post again:
what i meant by it doesnt store the achievements was it doesnt store the superficial ones like bowling a turkey, avoiding 4star wanted level, beating a friend at pool etc... the mission ones are obviously recorded.
i quickly skimmed over the 2 ps3 lists, they look the same to me.
