There isn't enough space to list all the games I have. I've been an avid wargamer since 7th grade and have way over 600+ games both board and computer. (includes those for Atari & Commodore)
I also used to collect Chess sets and have 11 of those as well.
But I will list some of the games I have for the computer and leave out board games for now
Duke Nukem 1 & 2
Master of Orion 1,2,3
Empire
Empire Delux
Shogun
Shogun Mongol Invasion
Medieval total war
Medieval Viking Invasion
Diablo 1,2
Europa Universalis 1,2
All kinds of Civil War games, Antietam, Bull Run etc
Pac War
Hearts of Iron
Quake, all of them & expansioins
Starcraft plus all expansions
Civ 1,2,3 plus expansions
Heros Might & Magic IV
plus numerous others
just some ideas Mac
