Honestly, its good for a game from a lob time back, but why didnt I rate it higher? In app purchases. You almost REQUIRE them to complete the game. Sure, its completable with out any, as I reached level 24 without them, but the challenges may require you to buy someone (my experience was it telling me to buy tails for an achievement) and everything is overpriced, too. Tails is a whopping 45 red star rings, and the game relies a bit too heavily on internet. I will recommend it because the games fun nonetheless, but who wants to play a game with so many purchases?
