Social City was a real-time city-building simulation game developed in association with American studio PushButton Labs[2] and published by Playdom.
The iPhone version was developed by Playdom in their Mountain View, CA office.
It also has Neighbour events and an advertising box, which has adverts to other Playdom Games and things that are coming soon.
It also may have an advert for ‘’Citybucks’’ The game uses two different currency systems; "Coins" which can be earned by cleaning buildings and collecting goods from factories - and "City Bucks" which can be bought with real money or obtained by completing surveys for the purchase of additional game items and upgrades.
Much in the way of other Facebook applications, Social City relies heavily on the player adding neighbours.
