I played as the human faction (red) and completed the game in 5 months. What can I say? It's a serious undertaking, and it's impressive. It's a shame, though, that the buildings that increase creature production don't seem to match the castles, and the lumber mills and mines are placed too far away and with inadequate protection for the first week of the game. Perhaps that's why (plus the uneven terrain) the AI develops slowly, and in the end, the game boils down to simple chases and bullying weaker opponents. However, as they say, a good meal is best enjoyed when you're hungry, so thank you to the author for their work.

By the way, if you're going to continue working on the map, it would be good if the castles in the dungeon, located in the corners, matched the castles outside. Then the AI will be well-equipped and quite dangerous. If you fix all the mistakes mentioned here and above, I think the map will be excellent, I would even say it will be eventful. Creative success to the author (without "complaining").
