Make War, not Consume

i agree too. maybe through craver population quest chain rework, we can integrate craver's planet devouring instinct(like uses cravers as short-term exploiting labor or soldier thing)

Yopp GibletHead, I doo that to.
But I want to make use of them. Because in this moment they are a pain in the neck for the non Craver players.

I think it's a big problem right now with games that include Cravers; we can't get rid of them (unless we uncolonize the world they are on) or turn their consumption off. When Cravers are conquered by a non-Craver empire, they should lose their extra consumption (because it's very undesirable if you don't plan on invading the whole galaxy). 

Yeah. The way I see it is thus: Let's say I take over a planet which has a craver population. - I'm not sure how much a pop counts for, but a billion individuals seems about right based on how many you can fit on a planet. - Now my government is in charge and they move in a bigger population, and the cravers are in the minority.

At this point, my lot really aren't very keen on the Cravers demolishing the planet. If it's not illegal already, they're going to make it so. I think at this point it becomes hard for Cravers to keep depleting the planet. - Before it was a government-sanctioned method of generating resources. Now it's illegal and you're doing it for - what, to generate resources for a government that you don't agree with? It's not worth it, surely?

So, the Cravers either stop, or are incarcerated or put to death if you can't make them stop any other way. I'm certainly going to prefer one of these options to the cravers continuing to rip my planets apart under my watch.

So, from my own RP perspective it seems like they shouldn't be able to do that.

[edit] I just noticed that the second comment here would be about making it a law. That would work with this idea, although those law slots are rather precious... [/edit]
