FusionFall: Cartoon Network Universe is a massively multiplayer online game designed to combine the character development and open-world exploration of role-playing games with the action of traditional 3D platform games. Players begin customizing their own in-game avatars and then joining animé-infused versions of popular Cartoon Network characters as they try to save the world from a massive alien invasion. Gamers level up their characters by collecting small, deformed versions of the Cartoon Network stars. These "Nanos" offer ability boosts and power-ups, and they can be equipped in a multitude of different ways in order to solve unique challenges. Teamwork and social interaction play a large role in the overall experience, but unlike many other MMOs, FusionFall was designed with a specific goal of appealing to casual gamers who play for short periods of time. ~ Christopher Brown, All Game Guide
