Toy Box Metropolis is a simplified version of Simcity that takes place on the floor of a child’s bedroom. At the start, you are given your choice of objectives for the game. You then build roads, buildings, and landmarks in a way that will achieve the goal you set at the start of the game.
It is a pretty fun game, although music gets annoying after a couple of minutes. I could see elementary students using Toy Box Metropolis when they are studying towns and cities. The game could also be a group activity.
