how many had you captured?, and how many level 5 cities?
hmm..I had not considered to count until you mentioned it. I killed off 5 factions while Tarth killed off four + a minor faction. I am playing with a created faction--just having some fun waiting for 1.1.
I have 6 level 5 cities & 8 level 4 that will probably hit five before I wipe out Tarth. I have not actually looked because once you have that many cities it's not realistic to micro manage all. I focus on keeping gilder & food on the plus side. Food can be difficult because when you take over mismanaged cities they can drain your resources so I am balancing the capture/raze factor to stay in the black--plus i don't want stray pioneers establishing cities just to be a thorn in my side.
This game crashes about every 10-15 turns--depends. I am looking for the stay auto explore unit that may be causing this. Honestly, I am just trying to finish this off before 1.1 comes out
