Same with the maps, the more complex maps would turn into a silly game of people being completely lost looking for the bombing sites, trying to find each other and not knowing were to go.
The same maps and weapons was the only way to have a direct match with full action.
Anyway there were some more maps that were usually played beyond dust and aztec, like dust2, italy, inferno, nuke, cbble, and also the fun ones like rats, or the ones that changed a bit the rules of the game, like pool, sniper maps, and so on.
But you could tell that you were playing cs too much, when you found yourself playing jumping maps...
I think Medal of Honor: Allied Assault came out in a similar period and I ended up playing that for longer. I'd go back to playing dust on CS occasionally though - as a one map wonder it was good.
Occasionally today I'll turn an Xbox on and play some Battlefield, but I do miss FPS games of that era on a PC, with Teamspeak or whatever else we used.
