In the middle of week 2, he decided not to continue due to a lack of prospects (the only road from his castle led to an adjacent zone, to which I also had a direct path). That's where we met.
Although he managed to build Behemoths in week 1, and I only developed up to Dwarf Cottages, I had several Mages with 3-4 SP and GM2 with Lightning Bolt.
I could wipe out his entire army with Peasants on fakes.
Scouting revealed that from his spawn there was a second road, which led to GO and to another adjacent zone, but it was generated awkwardly behind the mountains, and getting there would have taken unrealistically long.
P/S: The rules on SM need to include a clause about a tech restart if there is no road to GO. Such buggy generations leave an unpleasant aftertaste from the game.
Thank you for your time.
