Gameplay-wise, this game is the natural evolution of Bayonetta 2, with more and better combos, better non-hack-n'-slash segments (the opera scene was genius) and the unexpectedly great Demon Masquerade and Demon Slave systems. Story-wise, it clearly is a deviation from the original duology's plot, but it ultimately makes sense because of this game being [spoiler]. The ending was one of the most beautiful ones I've ever seen in a game, and a great closure for this era of Bayonetta.
