For some PC RPG's, check out...
Ys: Oath in Felghana
Ys: 1 & 2 chronicles
All available on steam. Ys: 1 & 2 are the first games in the series dolled up and changed around a bit, and play much differently from Felghana or Origins. Felghana is when the series really changed up and became an action RPG series known for fun combat, hard bosses, and kick ass soundtracks. 1,2, and Felghana involve the same main character, but you don't have to play them in order - though if you so i'd suggest 1>2>Origins>Felghana.
Trails in the Sky is getting a PC release come early 2014, and is a great RPG that was originally released on the PsP in the west.
