Key points: 1. The closest we are likely to get to Master of Magic for iPad.
2. A significant improvement over the initial PC version - "Worlds of Magic"
3. For those who like fantasy 4X its a good, but pricey, buy.
4. Wizard AI now varies a lot. Some very tough on offense. Others try to make treaties with human or other wizard AI players.
5. Unlike some recent games Wizard AIs often fight each other.
6. A very deep game with many paths to try.
7. Some minor bugs left but overall very stable - I am playing on an iPad air 2 and iPhone 6 - I have no data on how it plays on earlier devices.
