First, the game can be played offline, no connection required. The character used for the offline version of the game will not be useable in the online version of the game for obvious exploit/hacking reasons. We are going to investigate ways to export your online character to the single player version of the game but the offline character will not be importable into the online version.
Second, the offline single player version of the game for those who purchase it through KickStarter will not use any form of DRM. We had been holding off on committing to that because we don’t know what our final distribution system (Steam, GOG, etc) is going to be and some of them use DRM. We may have DRM of some sort on post-KS sales but we’ll commit to keeping KS versions DRM and “phone home” free for the single player version once launched.
Third, the offline single player of the game will not have any microtransactions. We know this is kind of a no-brainer since it is offline but we wanted to be perfectly clear on that since there was some vagueness in a few statements in one of our video chats.
