I'm also interested in finding more PC jrpgs, here's what I found so far:
Heroine anthem series (no known translation)
Rance series (especially sengoku rance, hentai/jrpg types are fun)
Recettear, chantelise (recettear is better)
Utawarerumono (it has a translated jrpg tactics game)
Magna carta (partially translated)
Cross hermit (no known translation)
Langrisser series, growlanser (no known translation)
Bravesoul (hentai rpg)
Ys series (some of it are translated)
Castle fantasia series (I think Castle Fantasia 2 has translation)
Hundred swords (translated)
Cosmology of kyoto (weird)
edit: I didn't include JRPG games you can play on emus, which there are plenty of. (I'm currently replaying Front Mission 3 for PSX and Makai Kingdom for PS2)
edit:
I wonder if its some kind of national loyalty. When computers and gaming systems came out TVs and gaming systems were made in Japan where as the PC and its stuff was American. As a result they wanted to buy Japanese goods for both nationalistic and economic reasons. (thats whats I've assumed all these years at least.)
Intriguing perspective. I never really thought that gaming could actually be affected by some sort of quasi geopolitics.
This sort of explains why even some techie japs eschew the practicality of a PC over it's juvenile console version of a gaming platform, since a console is practically like a laptop/PC with it's other useful utilities willingly tied behind it's back.
ie: You can't use the same console to run softwares you use for work & play. You can't use your console to mod and make mods for your games. You don't get a mouse and keyboard and you have to play most FPS games with auto-aim like a noob (lol). You don't get to play decent RTS games on consoles either. You also don't get to easily upgrade parts for your consoles.
It's like playing around in an enclosed playground while you're being watched by goofy authoritarian P.T. Barnum type overlords trying to quantify your 'fun factor' in the most profitable way possible.. >_>
