FF is what defines turn-based RPGs. Diablo and Diablo II fit the description, but I'm not sure if they're for PSX at all. Also, and this I'm pretty sure is only for PC (Windows and Linux) is Neverwinter Nights. It's a real time game overlaid on the Dungeons and Dragons rules. It is turn based, but not like you would think. Everything happens with rolls of dice and stuff, but it's all transparent. Fighting is real time too, with the turns behind it. I can't really explain it, but it's not really turn based. It's one of the best games I've played, the characters and classes are so vastly different that you can play it forever. Then there are awesome modules you can find online. I play it with visage sometimes, it's an awesome game.
