Well for me I mostly play aoe3 asian dynasties and mods for aoe3, WoL of course, along with NE and Age of Dynasties. I occasionally play aoe2, but mostly for the campaigns. I do have rise of Nations and Age of mythology, but I rarely play them. I have total war empire too which is cool, but that also hardly gets played.
If I want some nostalgia I play aoe1, which was my first ever strategy game. Or Populous: The beginning which I also played when I was young. Populous is strategy and god-power based game, developed by Bullfrog productions and released in 1998.
