Hmm, couple more PD games no-one mentioned:
Deluxe Galaga 2.6, and anyone hear of a game called
Cybernetix? It's like one part Defender, one part
Asteroids... really interesting, I play it to this day
(Thanks WHDLoad!)
James Pond series any one?
Another vote for:
Worms
Syndicate + American Revolt Data disk
Micromachines
