Not exactly the most encouraging words coming from a game producer, but Ubisoft's Ben Mattes is a realist in an industry that needs more of them. And he's uttering them on the eve of Assassin's Creed II: Discovery coming to the iPhone. This is the first game Ubisoft has published to the App Store. All previous Ubisoft properties that popped up for the iDevices came from Gameloft. When asked what changed, Mattes simply explains that "it's time for Ubisoft to take a real stand on the iPhone." It's a platform that is now so huge, Ubisoft can no longer delegate.
