could I?

[Conradus]

My roomate has a physical copy of the game on PC I was wondering if I could just use my account on his computer, is it bad enough that I'm paying a subscription do I need to pay to use it too?

Your account must be registered to a PC copy of the game. If it is, you can play it on any PC that has it installed. Accounts only registered to the PS3 edition cannot be played on PCs.
