Summary: Overall, the game impressed me. Caveat - I had fairly low expectations. I do not know anything about the cartoon network show so I will not comment on the storyline. The controls were relatively simple to learn, and the game was fun to play. There is 'animated violence' so this is likely not appropriate for young children. It was definitely worth the $9 (new) I spent on it.
Summary: This is the one thing my six year old son was consistent about asking for for Christmas so I reluctantly ordered it from Amazon. Being a licensed game I didn't really know much about made me hesitant. Anyway he just finished the game and I watched him play it and helped him out here and there. Story: Generator Rex is sent on a few missions against one of his arch rivals to rescue friends and so on. Can't get into detail since I didn't watch him play the whole thing.
