Its interesting to read this list as you can see who are at the "older" end of the spectrum from their choices. For me (given the time of the game as well as the game itself)..
Hybris
Blasteroids
Stunt Car
Nuclear War
Dungeon Master
On my original A500 (back in the mists of time!). Then later (when I got an A1200) I got into
Mega-Lo-Mania
Populous (1/2/PL)
SWIV
Eye of the Beholder
And then when I got my A4000
Alien Breed 3D
Anyways, thats my 2 penneth.
