I have been searching for IOS games which i can play on my mobile device having these two specific features. *1. In-game currency is actually valuable in real world .. that is an be exchanged for goods and/or services and/or cash some where some how. *2. accepts itune credit for in game purchases. 3. Allows for the exchange of in game currencies between participants (probably a market place where players list in game points,life etc for sale to other players and accepts their own payments methods) The third point is not a necessity for the type of game i want to play on my phone but it's addition will come in handy... I will appreciate any reasonable suggestions ... unreasonable are also welcome thanks in advance
