This scenario isnt quite "amash with flames", but it does offer another challenge. As another gamer who visits your site posted on the board...this map is experiencing the problem with buildings. As you start this map you should be able to build some buildings off the bat, but after a bit you will start getting these brown areas and then no building. The problem I have discovered is a building limitation. I have also noticed that when you reach this limit... existing housing structures begin to disappear. This prevents too many tents by counting the more advanced homes as only 1 structure...so you can see where this loop can exist. You advance tents and they begin to eat more food... possible taking away from others... causing them to de-evolve... thus causing another build to lose a part due to the limitation.
The challenge is to maintain the constant inlflux of people, unemployment, and lack of housing due to the limitation. So without writing you a book...here it is. Oh, by the way, this building limitation has prevented me from building much and exporting a BOATLOAD of weapons, so I have A LOT of CASH (300,000 + and growing rapidly) and there is 14,000 + population.
