It’s tough for a (mobile) game developer, both to develop and sell a game. Development and business are two different aspects and both might get way too complicated. You might be a thrilling developer and make an amazing game, but how good it is if you can not sell as it deserves, or not at all?
Lauro started a topic on Forum Nokia about how to make money with mobile games. Many people telling their ideas and experiences on the subject. If you have some words to say, please contribute.
I would also recommend that you read gameProducer, where you can get to know many practical information about game business.
Also we learnt that, refreshmobile has a mobile game contest for their mobizines with Â£2000 prize.
