Just use a ps4 controller on PC. I've done it before and if you ask me I don't think there's any difference tbh. I just think PC gamers in general are better with mouse & keyboard because they use it more. Anywho, I sent the request on ps4, though I'm stayin offline for the time being. If you ever see my online just shoot me a party invite and I'll join.
Console, PS4 here. And yeah. I heard FFVX would have coop some time down the line and my friend keeps oozing about it so I figure why the hell not. There's not really anything else out there strangely enough.
