World Domination is a Risk type game for your Windows Phone. It is a turn based game where you play to... well... dominate the world.
The game was recently updated to version 2.2 that took care of a few bugs and added options for 12 or 24 hour turn durations and an option to invite players using the public chat.
While the update to the Windows Phone version of the game seems fairly routine, what's neat is that a Windows 8 version of the game has been released that allows cross platform play. So you can start a game on your Windows Phone and pick it back up from your Windows 8 computer. Much like you can do with King Poker.
In order to use the cross platform feature, you'll need to go into World Domination's settings and get your account retrieval code. Launch the Windows 8 version, tap the "Already have an Account" option. Enter your Windows Phone screen name and the retrieval code. The two versions now should be linked.
