The amount of habitable planets around, and their distribution, is very frustrating to fine-tune. It should be a sliding scale but I don't find that to be the case at all. If I set it to "abundant", they are everywhere, and I find that to be too much. But if I set it one notch down at "common", they are nowhere. Literally 6/7 stars will have no habitable planets. There are, what, 6 different settings? Why is there such a massive gap between one notch and the notch next to it? I'm seeing this in every single game and it's frustrating beyond belief. If I don't set it to abundant, most of the time I can only settle about 2-3 planets total (on a large map). When I set it to abundant I'll quickly get about 15-20 planets (not even kidding). I need something in between these two settings.
