I don't know how people deal with the micro of x5 planets.
Life-seeded runs. They are really fun and actually competitive in 2.2 and hunting for good Gaia's can be quite rewarding and worth starting wars over.
Terraforming is still bugged on the beta despite the patch notes so it is depressing when you find really nice regular 20-25s that will get ruined when you convert them.
Just hope they aren't only viable because of how bad the AI is.
