So, like the title states, I'm wondering if I will have to buy the game more than once in order for more than 1 person to play it on the same PS3.

My girlfriend and I both intend on playing this game on our PS3 and I'm trying to figure out if the game is locked to one account or if anyone can play it on the system (obviously each person has a separate subscription fee to cover). I just don't want to be told I have to pay an additional $40 to play a game I already own AFTER I've already linked the copy I own to her account.

And please, not to sound rude, but I don't want your opinion on how you think SE should run the game or how you think it works, I want an answer from someone who knows what they're talking about and isn't about to screw me out of $40 based on what they think instead of know.
