Love this game! It's got chess level of balance, strategy, and replay. Asynchronous multiplayer lets you take turns when you have time. Each game has been tense and unpredictable. Challenge me as SojournX.
A MOBA on iPad and iPhone? Sounds like a good idea, which is why Gameloft came up with Heroes of Order & Chaos. Some technical bugs are all that stand in the way of this game becoming quite popular.
