I guess that means there should be a way to marry your sister...
As long as there is also a no humans at all option.Earth, along with an (at least partially) accurate solar system, when one plays as humans.
Comets should be a hidden spacefaring race that trolls non-spacefaring species by flying around their worlds. It should be possible to wage war on comets.
Better, being able to use comets to convince lesser species that it is a harbinger of the end times.
don't know if this has been mentioned before, but being able to escape combat would be nice....some games just have fleets meet and one side gets completely destroyed.....if ships get overwhelmed they should be able to have a chance to flee.
Considering that in naval battles in Pdx games the ships are capable of fleeing, I would imagine the same is true for Stellaris even if it is in space and not in water, given that your spaceships are faster though. Slower ships shouldn't have a chance to escape.. except they maybe start up FTL in time..
