Click the Amazon review link at top left of this description.Buy this game if you want to have hours of fun and don’t buy it if you don't have hours to spare ;)I love Portal 2 because it keeps me laughing while it challenges me to think.  Portal 2 expands on the original Portal experience, creating a world that initially feels familiar; yet as you progress along the journey and tangle with the clever challenges, all worries that things might be too familiar are swept away by the scope of your adventure and the characters you meet along the way. It's not always easy to out think GLaDOS!
