I've been busily making maps... but I would like to take it a step further and create some scenarios.
If the map editor could be used to place starting armies, set starting income for each player, and give one player multiple cities... you would have a full on scenario editor.
One would also need to be able to select between default setup (random units, no production, ect) and scenario setup.
It would be nice to have some asymmetrical starts...one player beginning with a horde of troops and gold, but only one city, another player with several cities, few armies and empty coffers (for example).
