Be aware of the fact that you didn't buy the game itself. You didn't even buy the disc. You rented the right to use the game. The game itself, the disc and everything you bought in-game (DLC) is still owned by Activision. It's not your's. Yeah, I got Black Ops II last week, and I got a bit bored, but I couldn't play the game, so I decided to read the purchase agreement. Turns out they can come to my house any minute to take everything away...
