Game Idea

After my learning experiences with the interface builder I had a great idea for a game which ill start working on. It'll probably involve learning how to set a server up to serve as a middleman to connect different players together so they can compete. Ill also have to do some research into how to do network programming with the IPhone. Overall it should be very exciting to make. My current decision I need to make is if I want to make the game using cocos2d or a viewbased app using interface builder.
