let's see.

I don't think some of these titles are really overlooked. Who doesn't love at least half of the Chrono series? Trigger is definitely my favorite non FF square title. Now that's a game.

Love the mana series. Part 3 is great on so many levels, I'd have to say, objectively speaking, 3 is the best hands down. but nostalgia prompts me to say 2 is best. My memories of 3 are from the age of 22, playing on an emulator. My memories of 2 are from early preteen years, playing on my SNES, when games meant a little more. Even if it was frickin excruciating to grind dryad from level 0 to 8 so I could beat the game =/ Not to mention the bugginess.

Xenogears has the distinction of being the first rpg I hated so much I couldn't bring myself to finish it. Couldn't even make it past the first disc. Hey, video game companies? Games are for playing. If I wanted to watch a movie I'd watch a movie, and it'd be a lot better than what you can pull off. What a miserable excuse for a game, and I hear the second disc is even worse =/

Ogre Battle isn't the best in the Ogre series, but the Ogre series overall is better than anything FF ever did, so that deserves mentioning. I'd have to say as a series, Ogre is my favorite because of Ogre Battle 64 alone.

Saga-- the gameboy games, especially II, are great. Romancing saga III as well. I absolutely love the level-up system of randomly learning new tactics and improving stats. I wish all RPGs were like this. Definitely my favorite leveling system ever. But until I and II can get frickin fan-translated already, that's all I'll play. Anyone with condescending remarks about how I should stop being an ignorant American and learn to read Japanese just so I can play a video game: go to hell. Seriously, just go right to hell. As for the "frontier" games, I was tolerable, but incredibly repetitive. II I didn't even bother finishing, probably because I was already worn out from having just finished I.

I'm just getting into Valkyrie Profile. The first game was good. I'm currently playing the DS game which has issues, but is fun. Doubt I'd have fun with it if I couldn't use savestates, and either way it has its issues, but it managed to hold my attention while I have several never-before-played RPGs on my computer waiting their turn, so that says something.
