Hey Ross and Happy Birthday (well, it has been two weeks, but i am never on time with these, so here we got).
I grew up in the late 80s early 90's, and much of my favorite Game OST's come from my time playing Amiga games. And some have awesome Retro-Tunes that are not in the posted lists. Maybe will enjoy some of them as much as i have.
Unreal (AmigaGame)
Shadow of the Beast -> Track: title and the plains 2
Organ Trail
Monkey Island Theme Song Yes, not obscure at all, but but i live it to death, so it had to be here ^^
Not a game Soundtrack, but from the slightly obscure Movie Ravenous. Love how the happy tunes mix more and more with sinister ones. But maybe you have to see the film to enjoy the music. In my opinion also a movie worth watching, even after 17 years it has been out.
