Former Microsoft employees Paul Bettner and his brother Dave left the Halo Wars project to create iPhone games with their start-up company, NewToy becoming the latest talents to throw their support behind the platform. "We quit our jobs because we believe in the iPhone. We believe it has the potential to be as revolutionary to handheld gaming as the original Gameboy was."
The ArsTechnica writer is not impressed by their decision to leave Halo Wars to create a Chess Game for the iPhone. I think they are just testing the waters with the chess game. Trying to understand the SDK and the dynamics behind the App Store. Also Scrabulous was one of the most populr games on facebook. There is no reason to think that small games will fail or will not gain critical mass.
