Civilian ships can certainly get as large as supercarriers because they lack several limitations, such as weapons or the need to make rapid maneuvers. I'd like to keep the size to a hard 1,000/1,500 meter limit for the moment though, so try to keep it in that bracket!

Anyway, I will probably start up the OOC thread in a bit, but I'm considering what to use as a map. One idea is to use: http://www.newsfrombree.co.uk/starmap.gif

...and writing out which systems belong to whom in the OOC thread. Perhaps with relative distances from Sol (e.g. 5 hexagons up, two right).
