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.
Yeah, the beta doesn't have many maps yet (unless you get the ones that have been made illegally with the stolen HL2 tools). It's Counter Strike but with updated graphics, physics, models etc., which make it a lot of fun
. When the final version is out (shouldn't be long now), it will definetly be an improvement over normal CS, as there will be custom maps coming out straight away, making it the perfect upgrade.
But normal Counter-Stike would also be great to play
