I see the box insert for the first time (still haven't got my copy). I am surprised there is no dedicated room for additional system discs.
That's weird because the expansions seem to be an integral part of the whole game system.
Or wells for extra cards (or sleeved cards), etc. You might cram some extra baggies of ships/nodes/etc in there, but this insert is basically going to get trashed the minute you try to add even one expansion to the box. I think they knew this, and that's why we have such a huge box to begin with. Plenty of room to homebrew our own storage and put several expansions in there.
