I know that's an unfair comparison to make when it comes to family-friendly games, but these kinds of games should be able to hold their own. The environments are passable, but you won't get lost in them the way you would while playing a game like BioShock. Some of the animations are a bit off, but the alien forms look pretty good overall. The character models are pretty much what you'd expect if you've ever seen commercials for the cartoon. Vilgax Attacks replicates the look of the animated series, but it's not an impressive-looking game. It's not a very deep game and it's appeal is limited, but when all is said and done, Vilgax Attacks is a harmless action/platformer that will please fans of the series. Still, a fair look at this game reveals it to be quite a decent one. If you don't care about the series, you won't really be missing all that much.
Ben 10 Alien Force: Vilgax Attacks falls somewhere between success and failure, though it leans much more heavily towards success than most other licensed games. For every gem like The Chronicles of Riddick: Escape From Butcher Bay, there are fifty games that deserve to be either forgotten or beheld as examples of how not to make a game. Licensed properties usually don't fare well in the gaming world.
