Why is there no way to regulate the types of planets ? You can choose how many habitable worlds , or how many planets. But what you can't do is dictate how frequent the size of the planets are.
For instance I like lots of habitable planets in my galaxy but selecting abundent in this causes there to be a lvl 16 every few stars. I still want good planets to be rare but I just want lots of planets. I would like to be happy about finding a lvl 10 or 12 planet instead of ho hum lemmy explore a little more to see if I find an 18 next star over. If you try and limit the number of habitible planets it dosn't seem to change the quality just makes it so 3 out of 4 stars are a waste of space.
It seems to me planets lower then class 7 are rare , not planets above class 10. I would like some way to have a galaxy full of barely habitible planets that are marginally usefull and you really need to specilized and give more value to those lvl 10 and gods smiling apon you the one 16 out of your 40 planets thats become the center of yoru empire.
