Yeah I don't think it really needs a remake.

FF9 was supposed to be about celebrating the classic style of JRPGs. I think trying to update it for modern sensibilities would ruin that. It's also aged better than any of the older games. Especially if you play the cellphone/PC/Switch version with the updated character models, it still looks great.

Literally all they need to do for this game is somehow remake the prerendered backgrounds in HD. Maybe using some of those AI upscaling algorithms, which can produce good results, but are a bit inconsistent.
