So it seems to me that there are a bunch of gameplay ideas floating about without a particular map attached to them. There are also a number of maps that would be vastly improved with better or unique gameplay. Therefore, I suggest that the Melting Pot have a sub-forum strictly for gameplay ideas. Mapmakers would be free to incorporate any or all of an idea posted on this sub-forum into their maps. I think this would encourage people to think outside the box and would lead to more maps with unique and fun gameplay.
As an example, here is an idea I have been thinking about (but please don't judge the merit of a sub-forum on the quality of this idea ): Consider an area in two different points in time, where a regional map would look very different. One could make a map of one era with a certain set of bonus regions, or one could make a map of the other era with an entirely different set of bonus regions (but the same territory layout). Anyways, why not superimpose the bonus regions on top of each other? So, if letters represented territories, bonus regions could be ABCD, EFGH, etc., and ABEF, CGIQ, etc. (if that makes sense). Someone with some artistic talent could make this a very nice map, IMHO.
