Here's the Order

LUNAR: The Silver Star
LUNAR: Eternal Blue

Then there was "LUNAR: Silver Star Story"; the first remake of LUNAR:TSS...

Then came another remake and a first remake for L:EB. They were (Bassically) "LUNAR: Silver Star Story Complete" and "LUNAR: Eternal Blue Complete"...

Then came along "Lunar Legend" which was a corny ass remake of LUNAR: TSS. It's way too different. By the way, LUNAR: SSSC is a kick ass game. You should get it...
