Lucky Train is a train simulation game, where you have to build your own train routes.
Lucky Train takes the gamble of building itself almost entirely around its social mechanic, which involves creating train routes and then adding your friends to them as “stops” along the line. You load trains up with passengers from your buildings, then send them on trips to make money.
All of the decorations available in Lucky Train are themed around the sorts of things you use to decorate a model train track: little buildings, trees, landscaping.
