Like the Grandia II port on PS2 after DC, Lunar~Eternal Blue port on PS1 after Saturn is sloppy. The awful PS midi music is on painful display, making the instrumentation worse than the Saturn or Mega CD versions even if the sound quality is higher. Think of the PC versions of FFVII and VIII that you've heard so much about. Iwadare's tracks are violin- and oboe-heavy, and they suffer a lot.
Mega CD Eternal Blue is significantly better put-together, with better art direction (remake cinemas are totally off-model), better dungeon design (original's mazes and architecture are delightful and maddening), and better sound direction (certain tracks are weirdly placed or overused in the remake).
Mega CD Silver Star is...a totally different game, with many flaws but many of its own merits. There was also a
Silver Star comparison thread, if it helps.
Maybe the
Lunar community thread should come back.
