I know that under the earlier versions people used to develop huge populations, especially of robots but since the planet class cap was introduced this has got harder.
Now we have a new toy the "Chimeric Biomass" to increase the class of a planet and the min distance between star bases has been reduced so they can be served by far more star bases (potentially up to 36 in the endgame if you're pragmatic and so increase the radius by 2 and add in the support field mastery tech and its +2 ability).
I was wondering what monstrous planets people have created and include one from the finish of my last game just before I completed the Ascension Gate.
The planet started as class 20 and the unused tiles are from the glorious Chimeric Biomass which I've just added. (Incidentally is the galactic mainframe a sensible use of the tile next to the capital?). I've been ignoring the Prelimbral Beacon Centre since don't need space monsters and don't want to use Arnor Spice for no good reason - I suppose I could delete it but it seems a bit sad to do so.
It's currently serviced by 20 starbases all of which have the full gamut of production bonuses (factory , zero scaling replicators, collectors) but much less research infrastructure due to the promethion cost.
Anyway, I'd love to see some other people's planets which put my effort to shame.
