The good: Bright colors, cute characters, and completely nonviolent gameplay make this ball-rolling fest great for any age. Even your littlest ones can have fun as the Prince of the Cosmos, pushing around his ball and rolling various objects into it to make it bigger.
The bad: Could encourage children to try to stick household pets and furniture to their favorite ball.
The premise: A plane crash sends you into an underwater dystopia founded by Ayn Rand analog Andrew Ryan. Deal with the crazed citizens of the now-ruined city and perform genetic experiments on yourself to survive.
The good: Little girls play a prominent role in the game.

The good: Historical fiction can get your kid interested in learning about the Crusades. Creeds can help encourage strong work ethics.
The bad: The main character is a professional killer who had his finger cut off so he could fit a spring-loaded knife on his arm. He isn't exactly one of the Wiggles.
The premise: Mario, Luigi, Peach, Bowser, and all the other Mario characters get together to play a variety of minigames in a colorful board-game environment.

The bad: They're still insane murderers. The only way to get around them is to off them yourself, making you at the very least a dubiously sane killer.
The premise: Shake, rock, swing, and wave the Wii remote through dozens of cartoonish minigames.
The good: Plenty of different minigames encourage shape recognition, balance, and physical activity. Multiplayer lets your child's friends have fun together with it.

The premise: A Marine Force Recon unit and an S.A.S. squad search for a terrorist ring leader and the Russian strongman who's backing him.
