This map was intended to be played against AI lords - giving them much gold, while human would be able to help himself by using special powers - ability to heal the troops and to get the gold shipment from Europe. You can play with or without allies, although fighting with a human lord by my side is my favorite way.
Note: this map wasn't created by myself. Lady Catherine did most of the job, while I only made it somewhat better looking by adding some shrubs here and there, and some few rocks.
Few more words: The idea with this map was to fight against AI lords, like we did it several times by now, only with difference that in this Extreme map there are no outposts. This one was meant to be played against AI lords with huge computer advantage, and human lord would be able to use special powers, although I do expect those powers to be used with honor. :) For example, human could restrict himself only to use healing ability inside his own castle, or he could receive gold shipments from Europe.
One could also edit this map to add a sighpost, and then to allow himself to receive reinforcements from Europe too (player would be placing his reinforcements near his signpost)! I just believe it wouldn't be fair our troops just to popup in the middle of the battlefield out of nowhere.
Our rules about arrow and stone falling from the sky should apply - we do not do that.
Those are just my recommendations, but you play it however you like. :)
