      OpenTTD is a transportation economics simulator. In single player mode,
      players control a transportation business, and use rail, road, sea, and air
      transport to move goods and people around the simulated world.

      In multiplayer networked mode, players may:
        - play competitively as different businesses
        - play cooperatively controlling the same business
        - observe as spectators
