Do you mean which ones I play currently, right now?
My favourite PC strategy of all times is Starcraft (the first one), no competition, but I don't play it any more.
Now:
Warcraft 3
Civilization 4
Civilization 5
I have played so many though. Command & Conquer: Red Alert was my first. Still love it to this day, it was such a trendsetting, awesome game back then.
Oh, and I loved Age of Empires, the Caesar series, Knights & Merchants (old as **** and I don't think anybody knows it today, but it was so cool somehow

), Stronghold 1 + 2, the popular German "Die Siedler" (The Settlers) series was really good and fun, I loved Empire Earth a lot for a while, Endless Space had a really cool concept and feel to it...
Can we talk more about PC games?
