The king of Wii games
The simplicity of the controls makes this game newcomer-friendly, and veteran players will not be disappointed. Super Smash Bros. Brawl takes the superior gameplay of Melee and enhances it with long-awaited (as well as unexpected) characters, fantastic music, and new features to the combat system such as Final Smashes.
Parents should not be overly concerned. For a fighting game, Brawl has a very non-objectionable combat system in which the goal is not to kill the opponent, but to force them off of the stage. Fighting abilities usually lack realism (e.g. cartoony explosions, futuristic weapons, swallowing opponents, etc).
