ERepublik

eRepublik is a free-to-play, web browser-based massively multiplayer online game developed by Romanian studio eRepublik Labs which was launched outside of beta phase on 14 October 2008 and is accessible via the Internet. The game is set in a mirror world (called the New World) where players, referred to as citizens, join in local and national politics where they can help formulate national economic and social policies as well as initiating wars with their neighbours and/or tread the path of a private citizen working, fighting and voting for their state. It was developed by Alexis Bonte and George Lemnaru.

eRepublik is programmed in PHP using Symfony framework and runs in most modern browsers. eRepublik has spawned a number of similar games due to the commercial success.
