The only PC games I know of that play like FF are....
Anachronox, I never saw the ending of this one....Couldn't figure out the final battle...then I lost my harddrive. You do have to level up all your party members....or the final battle will own you. That's probably the main reason why I couldn't beat it. And the game has a point-of-no-return...that I was stuck at, because of lack of saves. And Grandia II, if you can find it.
As for the PS2...
The closest match to FF10 would be Xenosaga (but with more talking, and more cutscenes....a lot more cutscenes...like, 75% more, with 25% being actual playing, or so it will seem for the first 15 hours.)
And Shadow Hearts....good game, but It feels better, if you've played Kouldelka, first. And I don' know about this one...I haven't played, it so I don't know how much like FF it is, but I may get it someday Suikoden3.
As for the PS1...pick one....but I like Xenogears out of all of them....Legend of Dragoon wasn't that bad and neither was Legend of Legaia or Valkery Profile. But all of these got repetitious, except for Xgears....the story was interesting enough to ignore the reputition, much like your FF games.
