For the sake of balance I have changed a few things in the map and rules:
-Catapults can now take all walls
-Alliances can win the game
-Lithuania starts with a slightly better army, but it has been repositioned.
-Lithuania now starts with a fleet
-Portugal start with a stronger army in Iberia, with a slightly increased income.
-Norway have a slightly bigger army
-Poland now starts with higher quality troops (replaced cavalry with infantry)
