Yes, and it's still the best FPS I've ever played, including all of the recent Battlefield and Call of Duty games and many others.
Find a good server (or servers) and stick with it. Hacks and general childishness gets banned very quickly, and people are a blast to play with overall. I'd still say it the best balance of weapon dynamics out there today - far from perfect, but MUCH better than the crap COD : MW2 gives you. Rate of fire, recoil, bullet damage, spread, etc.
Oh, and this thread's tags... "worst game ever?" Talk about laughable. Do you actually play the game or do you just watch it on YouTube? And by play it I don't mean jumped into a couple of games, got owned, and swore it off from there on.
