You are apparently Blind. Since Sonic Colors all of the full physical release games have done well and been good. Sonic Colors, Sonic Generations, Sonic All Star Racing, Sonic All Star Racing Transformed, and every Mario/Sonic game has been well received and were all fun. Colors, Generations and the racing games were especially great games honestly.
Sorry guy, but you're out of the loop and the old "sonic is terrible" meme died a few years back. Most you can do is complain about Sonic 4 at this point. Other than it Sonic has been back for awhile. Deal with it.
Well, all Sonic games are bad may be debatable, but are they console movers? In the quantity Wii U needs? It maybe a nice brick in the wall, like Bayonetta, but you hope this wasnt Nintendos Hail Mary.
