question BF2 server..

i never join to the BF2 server before cos dun have the CD key. n planned to get one later

question : is the server always full with player.. cos what i concern is this game is out for yrs even the special ops addon. so just worry tat after i buy the game, not much player in the server then i will lose out lot of fun

mean that after u install the game in ur pc.. unless u unistall it, if not the other person will not be able to use the CD key to access for online,

but my question will be how the hell the server know abt that? i know we cannot use the cdkey to online at same time but if different time.. can't we?

need to dl any client software in order to get into this?
