Whatever RNG is reduced in tactical layers is re-introduced on the geoscape. I am 30 hours in and have not found a second base. The one I can find via mission is on the other side of the map with lots of ocean in between. Some people stumble into their second base in the first few minutes. I don’t think a discrepancy like that is all that healthy …
Don’t get me wrong, I sure love the game … even if it does feel quite unfinished at times
