I'm choosing FF8 assuming they remake it in a similar way to the FF7 Remake. I've got mixed feelings about FF7 R, because I really think they changed it too much. What I really wanted was just FF7 with better visuals. However, I still have some fun with FF7 Remake, and I appreciate seeing the main characters all over again with updated visuals and voice acting. The combat system is fun too.
That is the sort of thing I'd like to see with FF8. I did really like the cast of characters in FF8 and I recall the story being pretty good too. I just really hated the combat and level systems so much though. They could overhaul all of that in a Remake and the game would be much better for it.
