FFVIII
(yep, that's it. told myself I need to clear some of the backlog before going crazy this time).
Wishing I'd bought more of the FF games - been replaying a number of them in anticipation of FFXV, but the user reviews (on Steam) of the SNES-era ones are abysmal (mixed or low-%-mostly-positive) on account of different sprites and technical issues like 15-fps combat and screen tearing. Already have the steam version of FFVII on PS4 (by which I mean it appears to be the same thing, what with fast-forward, higher-res models, invincibility, etc) as well as FFX/X-2 HD, which leaves FFIX, which wasn't on sale.
