to be honest... i think that K7 and SB39 are the 2 low points of the game, visually lacking and functionality is rather *meh* too.
that sad, pre F2P everytime i went to SB39 it was rather empty, felt like a ghost town.
since F2P that place is CROWDED again, lots of new player go through there and do their daily business there, i think it wouldn't hurt to touch that place up a bit.
add some spaceships outside the windows...
redo the lighting (i have no idea what happened but the lighting in K7 and SB39 both changed lately and imho not to the better)
oh and... get rid of those green skyboxes around both Stations and add some shiny Lens flare sun like DS9 has.
At least K7 on screen had no green nebula or planet or anything of that kind in the Background, just blank black Space.
K7 should have a full blown TOS interior kit instead of this generic 2409 interior look... so that the TOS Fanboys have a place to hang out on that fits their roleplay fetish...
