Starcraft 1 and 2, though they've been somewhat runied by time and bad update decisions.
Civilisation 3. The later games just leaves me cold, but 3 and to a lesser extent Civ2 are just great. After some massive modding of course... I can never leave a game unmodded.
Fran Bow, because oh my goodness... Just take a little pill now and see aaall the pretty colors, lol...
D2.
Supreme commander 1(with expansion).
Pirates! Original C64/128 and Amiga versions!
XCOM 3 Apocalypse. Most of the best parts from the first games, but with massively improved, almost everything else. And so much more fun than the modern XCOM remakes.
Transport Tycoon. Fanbased remake version is still HUGE.
Star wars Rebellion. Despite issues, lots of fun game, especially after some proper modding.
Pinball Dreams/Fantasy/Illusions series.
Dungeon keeper 1&2.
Settlers 3.
Imperialism 2.
I have absolutely forgotten a bunch, it's currently around 40 years since i got my first own computer so i wasn't limited to my brother's C20 and C64 and my oldest brother's Acorn Atom...
