Multiple planets is bound to not work. Heck, multiple continents can lead to some serious stagnancy.

Ah, I see, apologies for misinterpreting you. In my defense, I have seen a multiple planets setup actually work in the first Godhood - we just hit Space Opera very quickly.

On the topic at hand, I've always preferred great wheel cosmologies - they enable the aforementioned Space Opera period if that is the players' wont.
