Knuckles was not playable. Maybe just the modern-like introductions, particularly the Homing Attack. Personally, I would have liked the 16-bit graphic style appearance and gameplay from the earlier Sonic classic titles to be used for the Sonic 4 games. (There have been fan-made games from the fanbase and even one person to have remastered Sonic 1 and Sonic 2 as well as having created his own fan games who would be potential candidates for presenting a true sequel.
