Microsoft has also announced that a new Age of Empires Online app is now available to download for Windows Phone 7 owners. The app will let players of the game view recipes and stats for all of the game's craft items. It also has a materials calculator that lets players see which items you can build in the game with the materials that the player owns. Finally it lets players view the most popular craft items made by other community members and vote on their favorites.
Age of Empires Online, developed by Gas Powered Games, was Microsoft's first PC exclusive game it has released in several years and its first entry in the growing free-to-play PC game genre. So far there's no word on how many players the game has signed up.
