Can't chose just one...
In no particular order:
Power Monger - all expansion sets.
Gunship - I've lost sleep over this game.
Overlord ~ Supremacy - Favorite on the C=64 also.
The Perfect General - Board game without loosing the little cardboard pieces.
Warlords - Great multi player game.
Their Finest Hour, The Battle of Britain -
The Settlers - Hated it for hours...
Chaos Engine - Fun 2 player.
GODS -
If I had to choose one from my list, it would be a toss up between Gunship and Overlord ~ Supremacy
