There are only two games, actually.
Lunar: The Silver Star (a.k.a. Silver Star Story) - Sega CD, JP/US
Lunar 2: Eternal Blue - Sega CD, JP/US
Lunar: Silver Star Story - remake, Sega Saturn, JP only
Lunar 2: Eternal Blue - remake, Sega Saturn, JP only
Lunar: Silver Star Story Complete - port of SS ver, PSX JP/US
Lunar 2: Eternal Blue Complete - port of SS ver, PSX JP/US
Anyone else, feel free to correct me if I'm wrong. =P
My advice is to go for the "complete" PSX versions. There's tons of goodies in the packages, and the translation/presentation is top-notch. Lunar 2 EBC is still available in stores and should be $40. The first Lunar PSX title is available also, but *only* the game discs (as far as I know), and it runs $30, I think. The "complete" package of the first game has been out of print since the end of 1999.
Wonderful RPGs these games are. The characters are all quite lovable and the story is full of humor and in-jokes about pop culture. They've made me laugh out loud quite often, something not too many RPGs can do. Highly, highly reccomended.
