I still can't believe people think they can simulate the galaxy, along with its complex economy and events, on their own computer at home and play on it at the same time. I think the galaxy has gone mad!
It is very possible to do this, but the architecture of the software and systems would need to be very different from the online setup for it all to work on a client machine.
FD have already said it can be done with current systems, but it would mean a very severe set of limitations in the online version to ensure the game client is compatible with both offline and online modes - the only other option is create a brand new and completely separate offline game client/local server, which they have said they have no plans to do.
I hope they change their minds on that, and perhaps decide it can be done later on down the line after release - but it means taking away resources from the main game and expansions development......
Perhaps we shall get some kind of official response to the feeling of dissapointment (and in some cases anger) today - we'll see.
