Long ago I mentioned Kingdom Builder, which we have consistently enjoyed. It is a good board game for both hardcore gamers and casual players, with two players or a full table. I also mentioned that we bought the “Big Box” but only ever use the base game and first expansion, because to my mind the second added more complexity than its additional gameplay were worth; I have not tried later expansions.
Currently on Kickstarter is a Kingdom Builder Family Box, which is the base game plus first expansion for slightly more than the cost of the base game on Amazon. That seems like a pretty good deal. They also have a new edition of the Big Box with everything and some bundles with other games. I cannot speak to how great of deals those are, except for the intrinsic lust for More Board Games. Which I should resist.
This is one of those Kickstarters that is more of a pre-order than a project that would not get off the ground without your help. Queen Games is established and can meet a timeline, which seems like a rarity on Kickstarter. If you back, you will almost certainly get your games before Christmas. I do not have any connection to these people, I just like Kingdom Builder and saw it at Kick the Table.
