Hi there,
If ever, this is a game, called EDG6, that more or less requires liberty, I would go as far as stating it screams for liberty. That is much said of a tradition-traditionalist as myself. It is Bismarck on an unmodded Pangaea map with standard pace and size. All settings are on standard but quick combat is activated. There are three "red" AIs, two "yellow" ones and then two "blue-ish" ones.
Do you like founding cities? Here you can found 7-10 cities in reasonable locations. Do you like mining resources? Here you have almost all of them. What about NWs? You should be able to settle two of them early on. What about iron, horses, coal and aluminium? Here you have it all in abundance except for "only" two resources of horses. For oil you will have to conquer a little bit. But with liberty this is what you will do anyway… Imaging your own religion with two happiness buildings. Well, here you can possibly have that as well. Do you like it when barbs are stealing foreign workers and settlers? I played the map two times and on both occasions the barbs were good early allies. And if this was not good enough: the map itself is a little bit weird. Needless to say, early scouting is key. If you are ever going to play one of the games in this tree, I would recommend Sejong or this one. Have fun!
