Hello, You can check out our Blog post about Multiplayer Here. 4 Players are the max that you can have in one match. In Anno 1800’s multiplayer mode, up to four players can join a match to settle and conquer islands in an alliance or in a race against each other to reach the victory conditions first. .

having so few slots is quite frankly stupid.

Hello, We appreciate your feedback on adding more multiplayer slots. While we appreciate your enthusiasm towards this suggestion, please keep in mind that bumping is not allowed. Please take a look at our Forum Rules.

Hey lovro1966, we're currently not planning to do changes to the amount of players in single- or multiplayer matches. We're planning to release the coop mode in December which will allow you to play one faction together with up to 3 friends (which in theory could mean up to 16 players in one match). Maybe this is something you're interested in. Cheers,
