Minecraft is a great example that gameplay rules over graphics quality, although it does surprise me a little to learn that this game has already earned its developer $33 million. Not bad for a game that is still in beta.
Let that soak in: $33 million. All those dollars, slightly eroded by Paypal fees and taxes, come from around 800,000 alpha version adopters, who picked up the game at €9.95 ($14.26), and over one million beta version sales at €14.95 ($21.43). Currently, the Minecraft stats page lists 1,813,527 customers, pegging revenue at slightly above €23 million ($33 million).
