If it becomes the anticipated "nice earner", I think GalCiv IV is a given in due time - I have a feeling he's in love with GalCiv as much as an Owner/Programmer can be.
Constructing a storyline along the lines of ....
"After the violence of the final climatic battle, unknown to the Terran Alliance, a massive worm hole was opened up to a parallel universe where the Brutal Zargassian Alliance, and subjugated allies, saw their opportunity to mount a surprise attack through the worm hole ...... forced back to the Terran System, the Terran Alliance barely survived the brutal onslaught .... "
Rinse and repeat GalCiv with a brand new set of enemies and refreshed weapons blah blah....
Well .... one can dream .... stranger things have happened....
