Apologies if this has been addressed elsewhere - I did try searching but could not find an answer anywhere.

Basically, I have my one single S-E account, and on there I have my character (Cerberus) and my wife has her character (Moogle).

Now, we currently play on PS3 but at the end of this month I'm also buying the PS4 version (because I'm a collector), which will mean that I don't need to upgrade, and we can play on either PS3 or PS4.

My burning question is... given it's just the one S-E account, will I be able to play on one machine, and the wife on the other, at the same time?

Another question is, if I pay for her to transfer to Cerberus, will we both be able to sign in to my account and play together using our own characters?

Chances are the answer is blindingly obvious, but I had a very late night last night, it's very early now, and I'm soooooo tired.

Many thanks in advance!
