This is an amazing game, one of the best of all time, and it would be appropriate for younger kids if the storyline wasn't so dark. GLaDOS is a robot who will twist and manipulate you and later on the game, try to kill you with things such as turrets, falling cubes, poison water, and an attempt to incinerate you. Don't get me wrong, the storyline isn't so dark and twisted that it deserves an M, I think it is fit for a T, maybe even an E10+. Plus, it might be appropriate for younger kids, if they don't listen to the storyline on games really. But, it's not recommended for young kids. While GLaDOS is very manipulative, she is also likeable and very funny. The game is humorous, in a dark sort of way. GLaDOS is also creepy, because of everything she says, and what she has done (you will learn this at the end of the game, if you haven't already figured it out by the clues they gave you before you got there.) Overall, this is an amazing game, and even though it is short, I wasn't expecting a big 10-20 hour game on a disc with 5 games on it.
