I don't think anything beats Sonic Boom.
Was likely originally in development for PS4/Xbox One considering how much worse the final game looks from this footage from 2013. I don't think the Wii U could pull of what they were originally going for. Early screenshots already showed a downgrade, but even then it didn't look nearly as bad as what the final game looks like.
