I love the greater distances this will cause, ATM fuel colonies in my game were mostly just a way of saving the depletion of Uranus until the far future, but actually requiring harvesting platforms or fuel dumps to sprawl across your empire, well although that's more logistical complexity, it's pretty minor for what it adds to the game. You might lose a fuel dump and find your empire cut in half fir instance. I might suggest that when NPR ground assaults are given some attention they should be able to attack and take colonies you merely have resources dumped onto. Provided they are detected of course. Related to that, maybe the signature of a colony should increase due to resource presence too?
