I am currently working on a game that involves loading, shipping and selling goods. I am in the midst of selecting some mechanics to use, but am looking for some more ideas. One mechanic I want to use is to have three kinds of workers that each do a specific job (versus Agricola or Caylus where 1 kind of worker can do many different jobs). The three workers are the Loader, the Trucker, and the Salesman. Each player only starts with a single trucker, but throughout the game players can buy Loaders or Salesman to increase their efficiency and profit. Another central mechanic I am working on is having players load the trucks (similar to Zooloretto) but then having players do a silent bid on which truck they would like to buy. Any ideas you can give will be appreciated.
