With 3 players, remove the Cocoa Beans from the game.
With 4 or 5 players, remove the Coffee Beans from the game.
With 6 or 7 players , remove the Cocoa Beans and the Garden Beans from the game.
What's the logic behind this? Is there any reason cocoa beans only work with a medium number of players? I can see the potential logic of wanting to keep them occurring at a certain frequency, but how does that 'improve' the game. It they are common, players will scramble to get them due to rarity, and with more players they will be powerful in trade. These are key elements to the game, and I don't see why the rules specifically try to prevent these conditions that are just a natural part of the game. Same thing with coffee beans, why do the most common beans only work with a medium number of players? What effect will changing these rules have on the game?
