OpenTTD

OpenTTD puts you in charge of a transport company, building routes and arranging services to carry passengers and cargo. Railways, roads and other transport links form a network whose stations and vehicles need to work together. The game offers single-player competition against computer-controlled companies and online multiplayer.

This Android version adapts the interface for touch controls, including two-finger map scrolling while placing roads or stations. Dialogs can be moved out of the way when working on the map. It is a free, open-source adaptation.
