I love Lunar: SSSC (I never played the original Sega Saturn version, only the PS1 remake). Gameplay-wise it's nothing special, with your standard JRPG elements straight from the SNES-era. But it has such great characters (with amazing voice acting for the time), an engaging-if-cliche-story with great writing, and some of the best humor and localization of any RPG I've ever played. It's a cute, fun game that isn't all that long, so definitely worth a play.
