While Sonic Boom on the Wii U has its issues, there are also some redeeming qualities. Co-op is enjoyable, the platforming is pretty fun, and the 2D sections aren't bad. With a few more months in the oven and more polish, it could have ultimately been a decent Sonic title.
Unfortunately, the same can't be said for the 3DS version of Sonic Boom. There's almost nothing redeeming about it.
