I use the doubleg213 account for PS3 and PC mostly. But because I transferred to PC with that I can't transfer it to PS4.
So I created the doubleg213VANS account for PS3 jobs as it will also then allow me to transfer them forward if/when I get a PS4. It also means I won't be starting from zero again on PS4, the money I can live without as it's fairly easy to earn, but all the time unlocking the car upgrades etc. I just couldn't face doing again.
