Well seeing as this mod is about changing the history of Middle-earth, I thought it would be a good idea to find out what everyone would be doing in their first campaign
My first campaign will be as Harad. The first thing I will do is send an army or two, accompanied by a few Mumakil, north into Southern Ithilien and drive Gondor out. Then I'll send my troops to Osgiliath and, hopefully, win a decisive victory for Harad. After that I'll hold in Osgiliath andbuild my armies in the south.
When I get my armies to a good size, I'll send my Tribesmen, again with plenty of Mumakil, north to Osgiliath to join up with my other armies and launch an attack on the White City. At the same time my ships will sail from Umbar and the Corsairs will siege the city of Dol Amroth. With the fall of those two cities that will end any resistants from Gondor.
I'll spend the next while finishing off Gondor. Then I'll turn my attention to Mordor. Without any real land in Gondor, Mordor should be weakened. I'll surrond the Great Eye by attacking the Black Gate from north and Nurn from the East. Finally I'll launch an attack on Barad-dur. And I'll win, because I always do.
After that I only have one objective left. I'll send the Corsairs of Umbar north, to attack the port of the Grey Havens. After the conquering of Mithlond I'll probably help Isengard if they are still around and maybe take bits of Rohan for my own.
So post your ideas and strategies for your campaigns
