Hi everyone. I'm planning to play a mega-campaign with two friends, but I'm not entirely sure how to go about it. My question is: how can I make CK3 more engaging without creating blobs? I'd like to have something to do in every game, but I'm afraid that by the time the European phase rolls around, the world will be divided between the three of us. Do you have any ideas or experiences with this?
