Let us build a massive monument.

With the price of marble standing at 8gc and dropping and stone... well does anyone even buy it?.... it would be great if we could build a massive monument with our resources.
It could be as simple or complicated as programming allows.

We could set number of settlers to work on it ( changeable ) and keep adding different resources. It could be like The Statue of Liberty or Pyramids or Blackpool Tower. We could all make a unique monument. This would then start a tourist trade as friends pay to visiy our camps to see our monumets and buy scale models we sell in the little shop at the top.

at 1400marble for a gold mine and a possible 8 of them it makes it a necessity for those who rebuild them to harvest and buy vast quantities of this, hwp and tools. It's really the mines that keep the hwp/marble demand there even after you've levelled up all your buildings.
