Two very good ideas!(i promise)

It can be changed via map commands, but you'd need a program to automatically choose a random province to be the capital of a nation, and then choose which nation would start there, and then change the poptype into something suitable if you wanted to play random games.

You will be able to do this with the next version of SemiRandom. I already have the random start positions and custom god files. Adding poptype to the god file would produce the desired result. (Really wish we could mod poptypes at the map file level.)
