But it's one of the worst ports ever made for any great game out there, it's a different matter than Sonic 2006 and Sonic Boom (both 3DS and WiiU) that were bad developed original games.
Sonic 2006 had nice ideas that tried to complement the core gameplay from Sonic Adventure games, but most of them were cut (and badly cut) when SEGA decided to force the launch date. Problems with engine made the final game suffer and finally, most stages had killing bugs due to removal of gameplay elements from the final game and because actual development progress were halted to deliver the game "on date".
But Sonic Boom games had bland gameplay ideas that were badly executed, poor level designs, slow paced levels - I'm a veteran Sonic player and had to play the demo levels for like 10 minutes to end them, not even exploration focused Mario games like Mario 64 and Galaxy took that time to do one stage while not trying to get every item on them.
Essentially Sonic Boom 3DS and WiiU are the only Sonic's games that I'm skipping totally from playing in the entire franchise for now, to me they are as bad as Shadow The Hedgehog game and I think that I've got enough suffering with a Sonic related game with that one.
