Whew, that was a tense game :) But I had a better setup. In the first week, I built everything to the max. He came to me first with a group of mages, and then immediately took the artifact guarded by a hundred creatures of evil, even though I was standing right next to the artifact. After these battles, his troops were depleted, and... my victory.
Thanks for the game! (especially since I had to wait so long for it)).
