Vote for your best soundtrack! Keep in mind the soundtrack only, don't just vote for your favorite game.
Hard. But I absolutely can't play minigore without the soundtrack. I sing it under the shower. Hum myself to sleep with it. Seriously. Sound Reel did an amazing job. Spider and Zen bound are epic, too.
I am in love with Spider: Secret of Bryce Manor's Soundtrack. Developers say they'll release the SoundTrack sometime this year. Aside from that, MiniGore comes up second, with Cell & Love in Third.
