Sorry I might have missed it - but any feedback on those? In particular I was wondering, how were you able to assymilate them? 

For the moment, in Stadia OpenDev, If I well understood, you need to fill the patronage bar. After that, if the region of the IP is under your influence, you can use the Assihimilation button (and pay), to get the city(+ the region)

Ok, thanks. I thought I would have achieved that, but maybe there was something wrong with the influence over the region. Sounds to me like a pretty expensive endeavour nontheless.
