Size of the game?

There is something called offline mode in Steam.

Which unfortunately doesn't work like it should. I find it funny that you need to update your client on regular basis for the offline mode to work. Its oflinee for a reason, Valve!

No you don't need to update your client for the offline mode to work.

Well, for me it tries to update the game client when the network cable is plugged in, even if there is no network connection.

Works fine if Steam is started while the cable is unplugged.
