I was under the impression that you could build all 400 acres (the 280 that aren't already built) and explore the maximum 125 acres (soldier limited) on your first turn in protection. I just ran the numbers and I come up short on GC's. Can someone tell me which assumption(s) or calculation(s) are incorrect?
280 acres * 774gc's/acre = 216,720 for building
125 acres * 999gc's/acre = 124,875 for exploring
...and you start with 300k?
