For me, I'd have to say Old School X-COM (UFO Defense, TFTD, X-COM Apocalypse to an extent). I love them in a way that I just do not enjoy NewCOM, but the interface was quite possibly based on the recovered works of a 13th century scribe, and is very difficult to get used to for an unfamiliar player.
Since you can tolerate turn based combat I highly suggest Breath of Fire 3 and 4. I believe they're the best non-Final-Fantasy RPGs on Playstation, they're so good. Like Final Fantasy, each entry is a self-contained story so you can play any of them without touching the others. It's Playstation-era Capcom so you know the spritework is quality.
