Well each to their own, grown ups to mature games, children to the childish games
Hey, hold on, you just described every latest Blizzard game. No wonder there's so many children in the online communities. Oh wait...Everything about the game is easily grasped by any typical child. Easy to understand the story, easy to grasp game play, brightly animated characters and graphics, complete with 'DBZ hair.' It's not just the art style, it's the lack of depth and adult themes in the game design.
