OpenTTD

OpenTTD is an open source remake of the 1995 game Transport Tycoon Deluxe. In the game, the player must buy trains, buses, planes, and boats to transport people and goods in an attempt to make a profit. The game can be downloaded for free at openttd.org.

The game features singleplayer as well as multiplayer over LAN or online. There is also a scenario editor where players can create their own maps for playing. If there is not enough content, you can download mods inside the game.

On the Christmas Livestream 2011, it was the first game which was played, and it was played by Duncan, Sips (both of whom had newly formed channels) and Lewis. Lewis and Sips returned to the game on New Years Eve, and were accompanied by Simon and Rythian  (however, Simon and Rythian did not actually play.)

Sips, Lewis and Duncan played it in the 2012 Christmas Livestream, and this time were accompanied by Ridgedog and Mexxy.

In September 2013 Lewis, Sjin, Duncan, Sips and Ridgedog started another series. Posted on Sips' channel it has been struggling for views. This series has been infamous for players sabotaging others, this comes in the forms of land locking docks, destroying NPC roads and buildings and trying to ruin companies holds on towns.
