Hi. Got the game for my PS3 this morning. I came to play online, and it asked for my registration code, which I found. Anyways, the PS3 and game are really my brothers (he paid). We both have an account on the ps3 under our own names, along with registured Playstation Network accounts. If I used the online code with my network accuont, would my brother be able to use it with his account too, or would we need a second code? Cheers.
