I have to say "Record of Lodoss War" on the Sega Dreamcast. Yeah, it ended up just another Diablo-alike game in tone and gameplay; still, they managed a really high quality game that suffered mostly from being released in the waning months of the ill-fated console's lifetime.
As far as FF goes, I'll leave it at X / X-2 was the last acceptable title in the series. Everything since has been trash. ( With that said, I've heard good things about XV. However, due to them getting the rights to, and subsequently killing, Grandia -- I'll never give square another nickel. )
