What is your Favorite Counter-Strike?

[BLUEVOODU]

Alright... it's time to Vote it up!  What is your favorite Counter-Strike version?

I've been playing Counter-Strike since it was a half-life mod in 1999... and have been back into Counter-Strike 2.  There's a ton to love and hate about this game! lol  If you've played it, you know what I mean.  It's also the king of "Just One More."
