i seriously dont understand ... ok, i dont work for frontier, and like i ( and we ) dont know the coding behind the thing, but thats sound easy : the server acts as the data resolving, ie updating markets, missions , etc for the galaxy. All that could be done inside in-computer files, in-computer programs ( for offline play ), that would not even require internet connection ; you would play the game on your pc offline. the simulation would be the same as online, but all on your machine, only counting your interactions on. and to counteract, they can always sort of tweaks the offline single player mode so that the galaxy get events dynamicly by rules sets, rather than ''players''.... as online mode gather datas for all the players, offline would only gather for you; 1 player... anyways , frontier might understand what i mean ^^
