Frankly, FFVIII is one of those games that doesn't need a remkae. The graphics were done in a way where it'll be still playable down the road and the game itself was one of the more complete games in the Final Fantasy series. It doesn't need a remake for the most part, unless they want to fix the story...and we can all go on a binge about what needs to be fixed with the story.
Moreso than any Final Fantasy needing a remake, Chrono Cross is the one PSX Square game that needs a remake. Because it actually was incomplete. Only 3/4 the story was realized and 2/3 the characters stories weren't implemented. The game is still great (probably the best Square RPG on the PSX), but it could have been so much more.
