It's no secret that Retro Studios' Metroid Prime 3: Corruption is one of the most popular games on the Wii with it selling over 200,000 copies to date. How does a developer go about designing such a game, considering the hardware limitations of the Wii and at the same time maximizing its innovative control scheme?

Mark Pacini, the guy who directed the game, pointed out that developing the title had to start with a concept. He said that they set out to retain the Metroid feel of the game and at the same time "prove the controller". The biggest problem they had was not motion control, but on maximizing the limited number of buttons on it. Fortunately, they were playing around with the idea of a system where everything stacked:

We were already talking about a system where everything stacked: your beam, your missiles, the grapple beam — all the additional abilities you get for those weapons stack so you don't have to switch between beams, for instance. We definitely kept that in mind going forward because with limited buttons, we didn't want to make this game overly complicated.
