anyway: I got a question: how do you expand influence? I know you can build station to force it, but all other empires don't have to build a station on every single planet, while my empire is full of holes
also, it seems I can't assign systems to sectors for management
You build a station in every system now, it's part of the big changes in in 2.0 that happened about a year ago. Most of them you leave as tiny zero sized stations, only upgrading to real stations at important places or when you need certain modulus.
New in 2.2 you don't assign systems to sectors. Sectors are (somewhat awkwardly) automatically generated when you colonize a planet in a star cluster that doesn't have a system already. Also they no longer have their own resource bank, instead doing nothing by default (except seriously limiting the reach of the bonuses that governor leaders give, since leaders are now per sector instead of per planet, but in exchange have their cost tied to how large your empire is for some reason) although you can still give them permission and resources to automate them if you want. The idea is with the economic changes in 2.2 there's suppose to be less "pointless" clicking and things are suppose to be more based around actual decisions and hopefully less micromanagement, thus sectors would no longer really be needed and not do anything by default, but still there if you really want them. Personally I'm not sure if they really achieved that, but ymmv.
Hey, how's the new content, and how hard is the adjustment?
Imo the new content is full of good ideas implemented really poorly, like, shockingly poorly, and with zero actual testing. Although now, a month and a half after release, some of the more glaring bugs have been fixed, there's still a lot of serious flaws in implementation that I don't have much hope for us actually seeing fixed. Adjustment isn't too bad. Just take it slow, and probably it'd be best to read up on the dev diaries at least so you don't jump in blind. Economic management is very different, but not very complex or deep or hard to grasp.
