Just how does this actually work? Those who basically own the PS3 version of the game will not be required to pick up another copy for PS4, but do bear in mind that this is a one way ticket with no chance of turning back – once you have upgraded to the PS4 system, you are unable to access the PS3 version of the game any more.
During the upgrade process, expect the entire slew of data, ranging from characters to in-game items, to be carried forward to the PS4 version of the game, where you do so by registering the PS3 title to the Final Fantasy 14 service account prior to upgrading via Mog Station. You have until the end of this year to enjoy this upgrade system for free, but remember that time flies by quickly if we do not set a personal deadline for ourselves.
