Summary: This was purchased as a gift for my daughter, who absolutely loved the game. She played it for a very long time. I even found myself playing it quite a few times, until I finally completed it as well. There is not really much else to say about it, there are good review and videos of the game on the web to give you an idea if you will enjoy it or not, so I suggest giving them a search if that's a concern.
Pros: The game is fun, great for kids and adults alike, and a must for any fan of the Sonic franchise.
