I find that the randomized planet tokens is very imbalanced. Even if you use the expansion rule "more starting planet tokens" you can just end up with 3 poor planets with little resources like "VYCTOR V, EREBUS STATION, AVERNUS STATION", while your opponent can end up with a very rich planet like "PRIDEWATER".
I think a way to balance this is to seperate rich planets, randomize them, and each player can select one of them. Then he can randomize the rest and use them as the second planet pool of choices.
