I recently got obsessed with some music made for the OPN2, one of the chips modeled here - Yuzo Koshiro's soundtracks for the Sega Genesis:

The SOR3 soundtrack in particular showcases an avant-garde edge, closer to Autechre or Aphex Twin than traditional video game music, and generally more of a "club" aesthetic than anything I've heard in other 90's game music.
