what Dan said...
about the oberth.. your rabid fan/players might have noticed the U.S.S Tsiolkovskys crew quarters then, the ones shown are rather large.. even if it was officer quarters they are still larger than Capt. Sulus' quarters on the excelsior..
the newer smaller systems would give the room for not having to resort to such cramped quarters used in earlier vessels.
I would use Owens deck plans for the Oberth. they are are far more logical than a couple have seen.
as for the nova, well havent seen too many plans and didnt see enough of the quarters shown in shows to judge if they are way off.. but a couple plans i have seen -i wish i could remember them now- were quite nice and didnt see anything really 'anal retentive nitpicky' off on them..
god,grant me the senility to forget the people I never liked anyway,The good fortune to run into the ones I do,And the eyesight to tell the difference..
