Do people play mostly large games, 20+ planets? It seems the initial planet grab is over and action begins before I could really upgrade the progi... not to mention it wouldn't have time to colonize very many planets either. Not sure if most maps even have a planet with 4 resource asteroids - didn't regular ice/volcanic have just 3? And yeah Allure of Unity requires 8 civilian labs, I don't have room for those on my maps! 
What is the point of using resource focus on metal only or crystal only planets - doesn't the bonus apply to both types, and output is dependent on number of extractors, allegiance, etc - not on whether the planet is all single resource type?
Could advent be better tuned to large/late game economies than the other races?
