Well, there is always Septerra Core. I don't know how well it runs on modern PCs, but it was a fun little title in the JRPG style. If I remember correctly, it was actually made in Germany, but you wouldn't know it to play it -- it was even advertised as something that fans of Final Fantasy VII would enjoy. Also, FFVII, FFVIII, FFXI and FFIV all received PC releases. FFVII has the problem that Nobuo Uematsu's ground breaking score sounds crappy due to the tinny soundblaster midi that it uses, but is apparently improved in other areas. I can't comment on the other Final Fantasy games, except to say that FFVIII has a mini game included in the PC version that was otherwise impossible to play in the US, due to the Pocket Station, which is essentially a PSX version of the Dreamcast's VMU, never being released in the US.
Edit: <link=http://www.gog.com/en/gamecard/septerra_core_legacy_of_the_creator>Here's the link to the Good Old Games page for Septerra Core. If they have it, It's a pretty safe bet that modern computers will run it, or at least that they'll run the version they have for sale.
