The game itself was only 2 disks, lol. It also included a soundtrack CD and a Behind The Scenes CD. Lunar 2 had 5 disks: 3 for the game, 1 STRK CD, and a B-T-S cd.
Lunar Legend's still a good game. Just different graphics and stuff. Besides, to make up for the lack of the original BS, they added FF7-Style limit breaks, heh.
