I actually think of FF VII as one of the PS1 games that have aged the most, and far more to my eye then MGS. The 3d battle models are fantastic, but the overworld models are, like, laughably bad. It wasn't a hardware limitation either, because FF VIII and IX both fixed this with character models that actually look like the character, but VII looks like polygons are in short supply. They just didnt know how to fully utilize the system yet.
