In such wars you can take 50% warscore from them, or 25% warscore against human players who are not co-belligerents. If you declare war against an AI who is allied with a human player, you cannot co-belligerent them, and can take a maximum of 25% warscore from them. So if you're new and interested, please feel free to sign up too! Once we have a list of players, we can get to picking nations and start gaming! The base game is currently 80% off, and multiplayer games use whatever DLC the host has, so you could buy just the base game and enjoy all the DLC the host has bought. Please post in this thread if you would be interested in joining in.
We want players for another session of the finest map painter around, Europa Universalis IV, now that the Emperor DLC has finally launched.
