As per the subject -
Midweek Madness sale. I'm thinking of seriously whipping out the credit card here, however I have one question for which I can't seem to find an answer.
Can you play Steam games in a multi-player LAN environment without having to be connected to the internet?
eg. If I take my PC to our LAN night and the others were running a L4D2 multi-player game, would I be able to join if I'm using a Steam based version of L4D2 and had no internet access for validation.
Or are Steam games purely single player if there is no internet connection?
