An awesome underrated game from the MS-DOS era was Quarantine[0] (cyberpunk cab driving with super gore, funny writing and fantastic soundtrack). It was difficult to run due to EMS and free memory requirements.
That game has a special place in my heart. It's also damn near impossible to run glitch free on anything but a classic dos rig unless something has changed since I last tried. I could never get past the third or fourth map as the pass code did nothing. Very frustrating. But hell it was fun to play. The sequel, Road Warrior, was too buggy for me I remember and I didnt like it for some other reason. If any game needs a remake, it's that one. Omnicorp is all knowing.
I cite Quarrantine all the time, its logo was a master stroke of design, combining a steering wheel, the biohazard logo, and the letter Q.
You're spot-on about the soundtrack, too It was one of the first games that came on CDROM and used mixed-mode to put CD-DA tracks after the data track. Once the game was running, you could swap discs and listen to your own music, but the included tunes (from some Australian band, I believe) were great.
A few years ago I tried to get to the bottom of how Quarantine (made in Canada) ended up with a soundtrack of independent Aussie bands. Great bands, but bands that had a niche following, even in Australia, at the time.
I only got silence and a couple of shrugs in response to my emails though.
