There aren't a lot on PC to begin with. Obviously FF7 and 8 are on Steam, then you have the Ys games, and there's Agarest but I can't comment on it other than that it's in the tactical subgenre. There's Last Remnant but I haven't played it either. Look into Skyborn and Recettear, too -- the latter is only remotely an RPG but you might like it.
