The servers are all fairly poor quality and the game pace is too slow for me. I had more fun on the training missions than in the actual game honestly.

I like Enemy Territory Fortress a bit better. It is also a free native linux game. My only complaint about ETF is the guns are too weak. I like to plow somebody in the face once with a shotgun or automatic and leave them twitching like in counter-strike. ETF seems like endless circle strafing and you have to hit somebody 20 times to kill them.
