The best Sonic has been since Sonic Mania. Almost manages to one-up Mania by being made out of totally new stages and not re-tread any old ground (no Green Hill Zone) and the soundtrack is particularly good. The side stuff just isn't as entertaining or varied here however and the final boss goes on just slightly too long. Definitely inferior to Mania though I had a great time with it, if you're looking for an official 2D Sonic that isn't the original games or Mania, you could do a lot worse than Superstars.
