Populous Developer Making a New God Sim

Topia is an upcoming iOS game from Crescent Moon and Glenn Corpes, formerly of Bullfrog and one of the brains behind Populous.

So you can see where some of the inspiration for Topia is coming from. Pitched as "world creation simulation", you play a "god and shape the land as you choose, by the use of touch controls".

Looks relaxing!
