How would you like buildings to affect the environment?
Should buildings have a radius impression on the ground around them, such as: When a building is built, a bit of revealed earth/dirt appears around it.
Or on snow. A building would have melted ice around it, and thus dirt or stone would be revealed because of the output of heat that comes from that building. This heat melts the ice and reveals the elemental layer underneath.
When buildings are destroyed, should they leave craters in their wake?
Should the wreckage of a building stay for some seconds to empathise the destruction, if so how long should the wreckage burn?
Edit: Should we build able to build buildings on most terrain...even lumpy terrain with trees etc, or should it be like CnC 3 where you couldn't build them even on lumpy ground?
What are your thoughts/ideas towards this venture?
