Apart from opening the new areas, I'll just do what I always do: old advs and such.
Considering the feedback from testers about xp requirements and gains, I doubt I'll ever reach 75, at least it will take some years, so I have pretty much given up that idea. Therefore I won't bother rushing anything at all.
New military units will be a no-no for a long time for me. I'll only consider them if I get a huge pop limit increase.
I'm happy with getting more space. The rest if of little interest, at least for now.
