The board game Kingdom Builder is sold as a four-player game. However, the same game can also be played with five or six players with slightly changed rules.
Kingdom Builder only ships with tokens for four players. These STL files can be used to print additional houses (40 per player) and score tokens (one per player). They can also be used to replace lost tokens.
Suggested rule changes for five and six player games
Use six sections instead of four to create the map, and optionally have a one or two minute time limit for each move, violations punished by removing one house from the player's stack of unused houses.
