Cities XL Platinum

Cities XL (formerly Cities Unlimited) is an urban planning computer game developed by Monte Cristo, which already has experience with City Life. It was originally scheduled for release in the first quarter of 2009, but was finally released on October 8, 2009. The game allowed players to play online and interact and collaborate with others on huge persistent planets, trading resources or building blueprints to meet the needs of city dwellers. However, on March 8, 2010, the online service was closed and the game became a single-player-only game.
