2-Player and 3-Player buildings are not the best terms to use. 2 player buildings are used in all games, and 3 player buildings are used in games with 3 or 4 players. By design, I wanted a small set of buildings that was available in every game, to allow for simple setup. Some of the buildings just become too powerful in a 2-player game, and those buildings became restricted to games with more players.
Workshop, a straightforward building. A workshop can be used for just about anything, so it makes sense that you get one of each resource and $1. It made less sense when the game included lumber, and you got 1 of everything except lumber.
Cooperage, several versions of the Cooperage went in and out of the game, usually having to do with paying wood for something, but nothing that made it worth playing. Then I thought it made sense that someone making barrels would get paid more if there are a lot of whales. It had to be limited to one ship to stay balanced.
Brickyard, simply a place to get bricks in a large quantity.
Market, just another name for a building where you sell things
Bakery, I guess baking grain into bread is what makes it more valuable than the food you gain from the farm.
Inn, Stay the night, get up early the next day and get more work done.
Courthouse, similar thematically to a town hall, and a similar use.
Post Office, an old idea, sending letters around from place to place, and sending the building from owner to owner. I don’t know that that actually makes sense thematically. The post office in New Bedford was built in the 1830s, so it seemed like a good inclusion.
