Age of Empires Online was Released in 2011 developed by Robot Entertainment and Gas Powered Games.But it was officially shut down in 2013.
There are some Fanmade projects like celeste or penelope that allows you play the game on their server but they have the worse PvP Features with no Player Lobby(rooms, bad rating etc).
Are their any chances it could be a part of Voobly after all voobly has all the other previous Aoe games?
