Be a (simulated) manager: trade, trade, trade
The simulations genre (I'm not talking about vehicle simulations) wasn't that popular until SimCity and Populous came along. Both games started two genres: city building and god games.
With this update I'm adding a different type of simulation: trading sims. I'm not sure of the appeal of trading in a videogame as a major feature and I don't think these games will be downloaded a lot, but here they are.
