Spring 2014 season. Online ranked games (reports, discussions).

At turn 112, after navigating through numerous ranged units, I reached the green castle and destroyed the handcuffs under the protection of mages who were blocking the path to the city. I had to take a significant detour through rough terrain.
At turn 114, the detour turned out to be incredibly long. During this time, the opponent managed to build up their defenses, reinforcing with knights and ballistas, but it wasn't enough. At turn 115, I turned around. In essence, too much precious time was spent on maneuvers, detours, and searching for valuable resources.
I continued to attack until turn 125, where the opponent overwhelmed me with a couple of angels, 5 nagas, and a hundred skeletons. Game over.
