Make our life miserable

how many acres did you have?

I discover during 16,000A already 75k per building >.<
During 18,000k become 85k per building... Very pain.
All the $ sell military become building cost... No $ buy tech...

Caveman speak lol with less acres, im still making 7mil a turn. I wonder how much it evens out in express, cost of building and all that with more acres vs cost of buying tech and just cashing. What is the new acre sweet spot?
