OGame is a browser-based, money-management and space-war themed massively multiplayer online browser game with over two million accounts. OGame was created in 2000 and is produced and maintained by Gameforge. OGame is available in multiple languages, and different nationalities have their own communities. The game does not differ between the nationality communities except in rare cases. Players are generally informed of news, rule changes, or new versions through the official forums.
As of January 19, 2011, OGame.org has a total of 52 universes, including ten universes using the new redesign. More are being added periodically. The Ogame prOgame universe (Universe 35) has been discontinued as an exclusive for paying members, so anyone may now sign up for it.
