It seems to be Final Fantasy in general that's selling me a PS5, with Yuffie being PS5 exclusive and FFXVI being an exclusive looming on the horizon too.
I'm a bit concerned about how the Yuffie DLC will end up feeling gameplay-wise as they've said only Yuffie is playable. Part of the appeal of FFVII:R's combat system was swapping between characters on the fly, so it'll be interesting to see how that translates to a single character system.
