Thief Gold 
Thief II: The Metal Age  
Master of Orion II  
System Shock II 
The Neverhood
Sid Meier's Alpha Centauri + Alien Crossfire
Descent series 
Freespace series 
Any Black Isle game not part of the Fallout franchise 
Any Blizzard game 
Any Stardock game 

 Most people who are into 4X space strategy games favor Master of Orion II over GalCiv II.  MoO II is very old, however.
