Open source business simulation game based upon Transport Tycoon Deluxe.
Online multiplayer games are available, as well as a single-player against computer.
How to play: http://wiki.openttd.org/Tutorial
If you cannot hit buttons at the screen edge - calibrate touchscreen from the Mouse emulation dialog in the Chnage device config dialog at startup.
Touch the screen with two fingers to cancel current action, if you misplaced a road or a station.
This game is open-source - you may find sources at http://openttd.org/ or at my website.
You can install old version from here: http://sourceforge.net/projects/libsdl-android/files/apk/OpenTTD/
This game is not affiliated with the original Transport Tycoon Deluxe game, and does not contain any content from the original game.
Touch the screen with two fingers to cancel current action, and scroll the map.
Back up your save games to Google Drive, using Play Game services.
I don't know why does Play Games need so many permissions for that simple task, OpenTTD will definitely not manage your Google+ activity, and don't expect any leaderboards or achievements.
Also fixed minimap window and town authority dialogs.
