I learned recently that there is a rule stating "If there is only one bean card in one of your fields, you cannot harvest it as long as you have another field containing more than one bean card."
My friends have decided to house rule this out of the game, but I was wondering how does having or not having this rule affect the mechanics of the game?
For example: Does it influence the game length? How much does this change the implicit value of a 3rd bean field?
