PC's only?
There's Grandia 2 (not from Square, though)....
can't think of any other RPG console types for the PC.
Can get Dues Ex (DSX), it's a very good RPG, FPS.
If you like Console RPG's, you should get a PS2.
Kingdom Hearts
Xenogears (best PSX RPG ever, in my opinon)
Xenosaga (very good story, little lacking in game play...but the story is so good, well worth it, price just dropped on it, too....not Square)
FF9
FF10
FF10-2 (soon to come)
Star Ocean 2
Star Ocean 3 (soon to come)
FF7 (unedited text)
Vagrant Story
Legend of Dragoon (not Square)
Threads of Fate
