If you've played the original Lunar for Sega CD, I need only say: "Buy this collector's edition now!"  For those of you who are unfamiliar with Lunar, it's a classic old school RPG with 2D graphics and turn based battles. There are some differences between the Sega CD version and the Playstation one though.  The graphics and color have recieved a noticable face lift, some areas have been edited or cut altogether, and a few items have also been left out.  The music (a prime feature in the Sega CD version) has been reworked also, sometimes for the better, sometimes for the worse.  Another new feature is how you encounter enemies. You no longer are forced into random battles...enemies are now only in dungeons and can be seen by icons and therefore avoided in many cases.  Overall, this a great package even if the price tag is high.  The music CD and the documentary disc are nothing monumental, but fans will appreciate it.  If you have not played Lunar before and are a fan of RPGs, get this Playstation version while it's still available and find out why it created a cult following on the Sega CD.
