Basically, on the first map, I had 3 Necropolises and a secondary town at level 114 (a Citadel, where I built Aviary). By the end of the week, I had 1245 in the Citadel, and a stable nearby at level 125. We met. I captured the Castle (secondary town), built a Citadel there, and waited for reinforcements. My opponent didn't dare attack, so I eventually left and won.
Thanks for the game.
