(adsbygoogle = window.adsbygoogle || []).push({}); So I have a platinum save for NHL 11, and I wanna unlock the plat on my main account. Is it possible to do this with any game, and how would I do it?

Very few games can have their plat unlocked with simply opening one save. Megamind and Dead Island are a few exceptions...I haven't seen any trophy posts regarding the nhl games. You're probably out of luck with that game.
