Octopath Traveler II is simply a better version of the original. It expands upon what made the first game great while shoring up its weaknesses. That being said, if you didnt like Octopath Traveler then the formula is similar enough that you probably wont like the sequel either. This is an excellent take on the classic 2D JRPG and fans of the genre wont be let down.
