Ben 10 Omniverse is a classic example of a game that relies on a TV fan-base to be successful. Keeping in mind that the game is obviously targeted at boys aged six to ten, it succeeds on a few levels and fails at others.
The game does a good job at remaking the story elements and characters from the show. Players will play as young boy hero Ben, who has the power to temporarily transform himself into various alien creatures using a device called the Omnitrix. The game successfully uses this mechanic to add a layer of strategic depth to the game. Players will need to consistently use the Omnitrix power to win, and they will need to choose the correct alien form for any given scenario. There are multiple simple puzzles that will require the use of specific forms to overcome. There's nothing overly challenging, but considering the target demographic, simple is probably best.
The combat itself has very little depth. With some exception, combat revolves around mashing the attack button in order to stack as many attacks together as possible for maximum damage. There are some combos, and different alien forms have different attacks, but the basics are always the same. One serious lacking, considering the game's platform, is that it makes very little use of the Wii's motion functionality. All of the game's controls could easily be rolled into a standard Xbox or PS3 controller. While the game is available across consoles, its target demographic is most likely to have a Wii, and thus it would be nice to see more Wii-specific functionality. The control format, however, is easy to use and readily accessible, even to less-experienced players. The Omnitrix tool is a bit clunky at first, but not overly difficult to master.
Where the game really shines is in dialogue and characterization, which is taken right out of the cartoon. Many of the lines are actually quite humorous and would be downright hilarious to the target audience. Players will immediately recognize the voice and personality of their favorite characters from the show. The dialogue is also delivered in a classic text and voice-over format, so young gamers can read along as they play. This inclusion of text is a major plus for any children's game.
Graphics quality for the game is understandably cartoon-looking, but this is acceptable because it fits the cartoon quality of the original show. Level design and appearance is nothing spectacular, but it isn't something that hurts the game overall.
Repetition is what kills Ben 10 Omniverse. Targeting a young player demographic should be no excuse for simplified gameplay. The entire game consists of basically traveling to various locations and beating up on various alien or robotic enemies over and over again. There is low replay value and the multiplayer options are limited.
All in all, Ben 10 Omniverse is an okay game that will appeal to fans of the series and probably no one else. The dialogue is fitting, humorous and memorable, but intensely repetitive gameplay and lack of strategic depth will limit the game's overarching popularity.
