alright, now im thinking about making this idea into a mod (only the 40 zillionth project im working on. sleep being the 40 zillionth-and-one).
So we would be able to eventually get colonization of the worlds peacefully tho, right?(Ownership after enough culture time?)
with enough diplomatic relations under cultural influence over a prolonged period of time, you can acquire a neutral world peacefully
I have some balancing ideas too. @ game start you should be able to quickly ally with a neutral world (so you could bypass it freely), but should take time to acquire (which, researching and setting up culture centers and envoys might be enough, im not sure) as that is trade off for being able to do that. on the other hand, once you start acquiring planets this way, i kinda think you should have some sort of diplomatic momentum (Im imagining a burst of culture from the planet you just acquired peacefully, not unlike being hit by the deliverance engine)
It would be kind of cool to see a whole swath of worlds come under your control through diplomatic acquisition, but I also see that as unbalanced. I also think that for a civil setup, this is not costing enough money to be fair (you setup the culture centers, do some research, build 1-2 envoys and just keep moving them from world to world), but it also might be to slow to be effective. So how precisely to balance it will be the tricky part
