I’m not sure if you forgot them or that you just aren’t looking for
them, but there are some more EGA games: Hoyle’s Book of Games 3 &
Mixed-up Fairy Tales. And of course, Conquest of the Longbow, mentioned
already by collector.
Of the EGA versions, I’m missing CotL, Dr. Brain, EcoQuest, Willy Beamish & Mixed-up Fairy Tales.
If you’re interested, contact me. I’ve got a whole bunch of versions of
games since I made this Sierra version list once. Although you seem to
have quite the collection yourself (not many people have EGA versions,
KQ3 CoCo, etc.)
