Console exclusives have always been a big deal?
I mean, there was a brief period between FFXIII and FFXV where they were a little more lax, at least between PS and XBox. But they're really the exception to the rule. Since FF7 began it's new life on the PS1, Final Fantasy has been a Sony baby.
Really, if you're any kind of Final Fantasy fan, you have a Sony console. There's really no other excuse not to.

The fact that XIV is on PC is entirely down to the fact that it's an MMO. It kinda HAS to be on PC.
