If having a huge moon was an essential driver enabling development of advanced life and not, e.g., turning into Venus, then the expected number of others drops from 36 to well below 1.
If any exist (i.e., if other origins are possible, such as on Endor), we would only encounter expansionist cultures, because the others don't get out. If they all have controlled fusion (and how could they not?) they should have little interest in inner rocky planets, never mind the extreme primitives on them.
Look to the Kuiper belts, well supplied with frozen gases and extreme cold. Of the two, the latter is the far more valuable.
