Hello I will introduce to this online game of course its free :
eRepublik is a massively multiple player online, social networking and strategy web browser game developed by eRepublik Labs which launched on October 21, 2008 and is accessible via the Internet for free. The game is set in a mirror world (called the New World) where players, referred to as citizens, join in local and national politics, set economic policy, start businesses and wage wars with other countries.
eRepublik combines both social networking and strategy into a single massively multiplayer online game where players can participate in a variety of activities. Citizens of the New World can be employees, own businesses, form political parties, vote in elections, become party presidents, members of Congress or country presidents, write newspaper articles and even go to war as citizens of virtual versions of real life countries. The game has very few visual elements and is primarily text-based in nature.
