I am Setsuna is on PC, it is a cheaper buy on PC during steam sales.
Look into the Atelier games, the newer one seems to be pretty good. Digimon Story:Cyber Sleuth a turn based JRPG, a new Digimon game is coming out early next year as well. World of Final Fantasy, I mean ffs Xenogears is summonable! There is also the SAO games, I've been enjoying Hallow Fragment, apparently is 2 games in one or something, dunno. I haven't played Lost Song or Hallow Realization yet. The SAO games are unrelated to the anime story wise.
Tales of Berseria comes out in January but this will also come to PC as well.
