Paradox Interactive produced game, named Crusader Kings 3. 

This game is really funny, but it has really big problem: multiplayer doesn`t work good enough

For example, if you try to host a game, where are more than 10 players - you have no chance to finish that game.

Me, as a creator of a russian Discord server based on Crusader Kings 3, can say, that I can not make a game for 10and more players. At first time it works really well. But suddenly, after a couple of hours it can start crashing without any visible reason.

As I know, Paradox made P2P connection in Crusader Kings 3. Paradox should change the system. P2P system is when one player connects to the host, and another player connects to the first player, third to second. Like a chain. So if someone in this "chain" will have a bad computer/internet, other players after him in "chain" will lose a connection to the host. 

Other Paradox games, like Hearts of Iron 4 have different connection:
Everyone connects straight to the host, what makes the connection more stable. 

Also, I think, Paradox should add servers, that you can monthly rent, that could help with organising big multiplayer parties
