Since some people have shown an interest....
Here is one of the ways I like to play Dominions.
http://www.Dom3Minions.com/RandomMaps/MegaMap.zip
I will leave the other post out in general area for "wow cool map" posts. And repost here for some discussion on the methods, pros and cons of it.
It has 1495 provinces, 3 large oceans and 3 large land areas. You can play with all the other nations in your era and still have wilderness between you making scouting for them an effort. And there lots of impassable mountains creating chokepoints. It also has various surprises scattered around the map so be sure to SCOUT CAREFULLY before attacking a province.
I also added a short script that shows how I generated the additions that are scattered on the map. The "interesting.yab" isnt needed to play the map but if you have a YaBasic or some other basic then you might use it to generate surprises for other maps also. Or re-generate the surprises on this one if you play it enough to get to know whats there.
Warning: generating the world at the beginning of the game can take awhile
