I’ve been searching for a particular map, but haven’t had any success. However, I do recall some details about it. The map was designed for three players, with each player assigned a different color: blue, red, and green. As the blue player, you would start in the left corner of the map. I can try to draw a rough picture of the map from memory.
As for the demo version of the game, it was only available for the castle age and William Wallace campaign, with the Baltic map being the only playable option. The game was restricted to the castle age, and there were limited options for adjusting the map settings.
I cannot remember how I obtained the demo version of the game.
