I remember playing Septerra Core back in the early 2000s on the PC. JRPG developed specifically for the PC with some pretty awesome graphics. I did enjoy Last Remnant, even if it did get a bit repetitive. They also released FF12 on the PC I think, but I only got halfway through the game before it started playing itself (yay gambit system).
I really do wish there were more JPRGs and even fighters on the PC, even if they were ports. I've noticed with each console generation I personally haven't been as pleased with most of the games. With this generation I found myself buying almost exclusively JRPGs, some TRPGs and fighters, and the occassional odd game out (ie: Katamari, Little Big Planet -- only played LBP uhh twice ). Even then, JRPGs have been hitting a bit low on the mark as of late. Resonance of Fate is pretty awesome and quite a new take with some strong emphasis on tactics and positioning vice the usual active turn bar > Attack > repeat method. Would have been great on the computer with mouse placement of the endpoints and faster camera control.
Oh, and do get BlazBlue if you can. Great game, and can be played either button-mashing or technical depending on what you want to do with the game. IE: to complete all the endings I just button mashed with some idea of what I was doing for most characters. For time attacks and the like, I picked a few characters and learned moves/combos.
