I been getting annoyed by galaxy load of dead planet that is uncolonizable. I wish all of planet is colonizable but most will either be super low class (below 6) or extreme planet that require tech to stabilize it. Although this would make one mercenary that can turn dead planet into class 16 useless but it is just a small part. I do try with in-game option that increase the amount of habitable planet but still, most of galaxy will fill with dead planet anyway. Where should i look into XML to make this space magic happen?
