4X game, you start with one planet and build a factory, then next planet, then next and finally like 20-30 at what point you get a nervous tick each time you invent a new building since you have to build it manually everywhere and finally you decide to give the management of the planets to AI (at what point I ask what is the purpose of this planet management in the first place since the player don't want to do it anyway). It's boring and annoying and lame.
Let's say you start with 20 planets and by the mid game you got 100. How to make a system where you can manage them (and it's fun or at least not annoying, but preferably fun)?
