Once FDev fixes the economy to being influenced by everything in a system that will take care of my only real issue with colonization as it currently is. Not counting bug fixes, I am happy with how it works otherwise. The material costs are about right, but a bit high for t2 coriolis, otherwise everything is about what it feels like it should cost to scale. The megaships helped a ton, those were a great addition and make it feasible to do colonization at scale. I also am probably in the minority here but I actually like the 15 ly colonization range. Colonies should be constantly at the edge of civilization to mimic realistic growth, but also I understand that others want to play without the worries of powerplay. I think anything up to 50 ly range would be perfect for colonization, though new megaships would need to be added to compensate for the increased radius
