Isn't Counter-Strike source just Counter-Strike, albeit with shinier graphics and a lot less maps? I would certainly be down for a Counter-Strike get-together though. Bombing an innocent bunch of boxes is where it's at.
Also PT is correct, UT CTF is in fact a win. If anyone knows some excellent custom maps that rival the definitive flag-capturing experience that is "FACE", then please pour those guts of knowledge onto this thread.
The only thing that ruins FACE flag-capping is the bloody redeemer. :~
