Re: Half-Life 2 Purchase Options Revealed, CS:Source Full to come out Next Week
NV40, the games you listed are MMORPGs, which of course you have to play online since there's no single player. Having to be online to play a single player game is a bit silly, but as long as you log in to Steam once and choose "Exit", not "Exit and Log Off" then you won't need to be online to play.
