The first version of eXceed 3rd. The soundtrack is slightly different, and I actually prefer it to the remake's soundtrack. (Same basic tracks but the mixes and instrumentation and arrangements are a little different.) Also I think this version of the game is a little harder. Doesn't have the extra stage, I think, but I'm not sure (never been good enough to get to it in the remake anyway). Either way, this -- along with the rest of the eXceed series -- would make a lovely addition to GOG. Everyone one of them is a well-designed shmup with cool gameplay and snazzy music.
