I don't care how many times X/X2 has be re-released, I haven't played it yet other than a few hours on an emulator. So yes, I'll pick it up on Steam when I can.
What this really gets me excited for is that Square is actually looking at PC as a serious platform for release. I think it's very clear that Final Fantasy XV will make it to PC eventually. It's almost guaranteeable. Probably later in the future, but certainly at some point. That gets me really excited for Square's future games, what with DragonQuest Heroes also making it to PC. It may be that DragonQuest 11 follows suit. DQ Heroes not only launched on PC, but it launched at the same time as the PS4 release! Unheard of for Square!
If Squeenix can work out their licensing issues, I would LOVE to see Kingdom Hearts on PC. Tbh, JRPGs are the only reason I may ever buy an Xbox One or PS4. I have a strong PC, but I love JRPGs like Persona 5 and most things from Square's library. Seeing things like the new Tales games coming on PC at the same time as consoles... It gets me excited that in the future, more and more JRPGs will make it to PC. If anything, I'd love to see Persona 5 on PC.
