One Planet Challenge

[Lemmy]

Those of you who know civ may have heard of the One City Challenge (OCC) where you try to win the game, without ever building a city, or conquering one.
Now what if we tried it in SE4, but with one planet?
Anyone interested in taking the challenge?
The rules would be:
No conquering other planet
No colonizing
well, that's it, you can set everything else up yourself.
I think this would be easiest with the Religious trait, but it will take a long time to research alliegance subverter with only one world, so maybe first you should research ship capture, larger ships would also be usefull to, to use with remote mining.
