A free online game where you get to buy real-world streets (as long as they are on Google maps database) anywhere in the world. Some high-profile streets are either real expensive or owned by the game (so players can't own them). It's basically a giant advertisement for a new version of the board game coming out next year, when the online game is meant to disappear. Most of the streets in major metropolitan areas are gone, but you can make an offer to buy or sabotage them so owners can't get rent money (used to buy more buildings and properties).
