At the moment, my time is pretty limited due to both personal and professional matters, so I'm happy if I can make a train without extra time. In addition, my relationship with Superdeath has cooled down quite a bit. I had declared war on him 6-7 turns ago to get forced peace and safely accept caste in the GA, which he has refused to give me so far. Nevertheless, I accepted caste for a shorter than planned time. Maybe I should have left it alone, since SD is now invading me.
I discovered the visible army two turns ago. If it had moved to Björgvin-8 even one turn earlier, I would have definitely lost Björgvin. Now I might be able to hold it, even if it will be very expensive. It was a mistake that I only have 2 workers in place. In addition to the visible units, I have about 5 more units. I'm currently considering whether I should attack now or wait and how the units should be positioned after an attack or without an attack.
It's also interesting that he has completely emptied the city of Daemon and my chariot is right next to it.
Lindholm, on the other hand, cannot be saved. I was surprised by the strength of the stack here. He probably has all his units except for the city guards. I could possibly demolish Ghost for that (berserker and chariot on board). However, I wonder if I don't still need the units.
Looking at the graphs, I guess I didn't end up with neighbor luck. Picca is farming Greenline (4-5 cities) and Commodore is also making progress (several cities of Bing probably conquered with knights), while I can't get active with the highest power. If I survive SD's attack reasonably well, Picca should conquer most of his cities afterwards.
Looking at the geography, if I were SD (assuming you have ambitions to win), I would have tried to arm with me during the state of war, then in a forced peace, catch Picca's stack favorably, conquer Greenline's territories, and possibly demolish border cities.
The key word is probably ambition to win. Here it seems to me that the sole aim is to take the point leader out of the victory race.
It's also interesting that SD is spending all of his economic output on espionage against me. He probably had city visibility for a short time. After I researched machines for berserkers, I countered for a turn.
