If you like turn-based JRPG's then I recommend this game as a casual buy.
HOWEVER (and I can't stress this enough), bear in mind that the story isn't nearly as deep as the first game. Also, this version of the game (console version) is by far much worse than the original version (Champions of the Continent) because everything about CotC was designed with the gacha element in mind. Which sounds like a bad thing at first, but hear me out: In the gach version, you're given a LOT of free pulls. And you can get through the story with any character you want. The only real reason to pay for any particular 5* character is if you absolutely felt like you absolutely needed something. As a whole, the gacha element was largely just for aesthetic purposes.
Personally, I don't endorse buying a digital character because it's just money thrown away at the end of the day--unless of course you have the funds to do so comfortably--But I do think CotC had a better storyline and more interesting characters than this version (OT:0). This version of the game doesn't get real deep with the characters you pick up. The only ones that seem to actually matter at all are the 'Kindlers of Flame' ones that you start out with that are specific to this version and don't appear in CotC, but their story gets lost during the middle section of the game. It's pretty sad how bare the main story is here.
Anyway, as I said before, it's still a good game. It's just not an amazing or emotionally deep game compared to it's original version, OR the original Octopath Traveler game. If you're looking for a game to play that fills the itch for the classic JRPG turn-based niche--This isn't a bad one to pick up.
Just be aware that it's NOT going to give you the same feelings you had when you played the first one. That's for sure.
Tl;dr:
My grading for this game would probably be a C+. It's passable for a game and it's a fun time, but I would suggest getting it on sale. The story is disjointed and you probably won't feel emotionally invested in the characters you pick up along the way.
The music and visual style is still absolutely beautiful though.
