Actually, uranus is quite nice if you give him half a chance. Just ask him to leave you a nice little patch in return for continued neutrality or an alliance, and you're set. He literally controls everything to my west, and I don't fear him attacking me at all.
I fear him more aggressively taking away all the nearby potential colony worlds than outright attacking, but anyway he doesn't respond to my messages.
Problem is having to deal with this in the first place. The power ratio between oldbies:newbies is rather higher than in your average game. Except I can't think of anything that would solve this issue without creating extra problems, like being frustrated with a colonization system that seems to work good at first but gradually becomes less effective.
