iPhone gaming may still be in its infancy, but that hasn't kept some companies from trying to lay the foundations for strong franchises nice and early. Take Namco for example: Pac-Man: Championship Edition marks the fourth Pac-Man game on the iPhone in little more than a year. And while Pac-Man Remix (the last Pac-Man game on the iPhone) brought in some fresh gameplay ideas, Championship Edition is just another port of a game we've already seen before, isn't it?
