Well this has been a fun post to research
I went through the list of games on
The Amstrad CPC Games Resource to find all my old favourites and then compared that to
HOL. I was pleasantly surprised to find many games that had been converted that I hadn't known about before!
But to the point. Here's my 8-bit MIA (Missing In Amiga) list in no particular order:
Solomon's Key
Get Dexter! (aka Crafton & Xunc)
Highway Encounter / Alien Highway
Jack The Nipper
Psycho Pigs UXB
Slap Fight
Thrust
Revs (wasn't released on the Amstrad but still good
Way Of The Exploding Fist
Yie Ar Kung Fu
Wonderboy
Knight Tyme
Also worthy of mention are a couple of games who's sequels made it to the Amiga even though the originals didn't:
ATF
Druid
Gauntlet
Gryzor
Spindizzy
