Not sure if this game is forgotten or not, but I've only ever met one other person (who was not forced to play it by me) who has played this game.
Truly, this is (to me) pretty much my favorite RPG. It's fairly simple by modern terms (no leveling up, no skills, just very specific equipment-related builds and ship classes), but it was really a game that allowed and encouraged you to do as you liked with no real moral high ground that you had to stick to to get the "best" ending. All the endings were different and distinct, depending on your actions, and even after the game was over, you could continue to play and do whatever you liked.
I probably sunk a couple hundred hours into this game as a kid. And even though I started out with a copy that I had obtained from a friend, I bought another using a month and a half allowance money (which I had to mail to them because I didn't have a credit card) because I wanted the developers to have a sale from the good time I'd had. I can't think of any other game that I went to such lengths to pay for.
