Whoever said Tyrian get my love, and also Raptor has always been one of my favorite games. I only had the shareware demo as a kid, but I played the shit out of it.
EDIT: I just remembered that I got a CD-ROM when I was a kid, which was called simply Shoot-Em-Ups, and was filled with about 50 games or so, for DOS (or sometimes Win 3.1), that I played over and over again. It should still be at my parents house... I have to look for it next time I'm there.
