I searched and can't find a clear answer on this.

I bought the PC version of the game. But my son is considering playing.

If I buy him the PS3 version, can I use that version as well with my account created by registering the PC version. And vice versa? Can he play on a PC version with his account created for PS3?

One would think you could as long as I have an active and current account, but as I'm new to FF, figured I'd better ask.

Thanks in advance!
