San Francisco Rush 2049, Red Faction...some definite gems there.
Oooo...I thought of another one.
Raptor for the PC. It was 4.99 bargain bin...and I was a poor kid in need of something to play... I didn't have money for a genesis game but I also had a shitty 486 back in 1995. The game ran beautifully...not to mention it owns serious ass off every SHMUP game up until that point. Great game.
