a lot do play cod2 but if you remember when that came out everybody was up in arms due to the bugs and crap, there was even a server shut down by almost all to show what bs the game was..
that was to get them to run punkbuster as it wasnt in the original release, and pb has been added and bugs have been fixed with patches.
cod2 weapons are less skilled or easier to use (sniper can kill someone with the wind of the bullet,dont get me started on shotguns)
thats because snipers are powerfull, and look at the AWP on css. cod2 snipers do what they were designed to do, take someone down from a long way, and guess what that means, it means its a powerfull gun.
and shotguns are devastating close range yes, because thats what they are designed to be, but step back and use a gun from normal range and a shotgunner is useless against you. i use a rifle, and unless im in open ground or in smoke, chances are i'll take out the shotty.
and oh yea no-one plays it anymore, its just the no.1 most played online fps on xfire.
