GameTrailers is usually very good with their reviews I think, but I never saw a review of theirs on a Sonic game I thought that was decent. I am not sure what to say about this one, but comments like "Longest Sonic game in recent memory" and "Five hours" are not right at all. Sonic Adventure is around ten hours and Sonic Unleashed is around twenty!
I was expecting not to get this game, but I will most likely be able to play through it sometime next week. I am sure I will like it, but there is a lot of things I hate as well, like how Sonic can swim now for some reason.
