The TtS! Kingmaker is now in its sixth and final week, and the players have ratcheted up a mighty 35 online Wars of the Roses battles between them, so far!
All of the terrain is based on WotR battles, as are the army lists. Antony Spencer, who designed, organised and is running it, has written a summary of the campaign, so far, including a campaign map. You can find it at this link on the TtS! forum. Fascinating stuff!
