I seem to be unable to host a game of Natural Selection whilst my steam is in off line mode? Why is this? It's rather frustrating as I don't have broadband so I can't play online, it seems as though I need to be connected to the internet for something as simple as playing against AI, running a LAN game or whenever I want to try make a map?
Is this a bug in my installation or a security measure against piracy? If it's the latter then why is it stopping me from playing seeing as how I have a genuine steam installation and CD-Key for Half-Life 1?
