Original VII is great how it is. I was happy to have an alternate telling for the remakes.
Unlike VII, VIII has always been ugly and needs a graphical upgrade to match their over ambitious models for the hardware. Also needs a combat overhaul so it's not so super easy, and draw is not so tedious.
Tactics original is pretty, but could use some QoL updates.
I don't agree with this. It definitely wasn't considered ugly back when it was new. In fact, I believe the over ambitious models for the hardware as you put them were considered a big improvement compared to VII's.
