Originally I wrote a huge review about this game because I love it, going over every detail in every way. But then i accidentally clicked off and lost all of it. So here's the cliffnotes version:
Octopath traveler is a fantastic game in every way with the most fun turn based combat I have ever seen that is complex yet fun for players of all skill and knowledge levels. The characters and world and incredibly well written and make the game feel like it takes place in a real universe out there. There is a ton of customization that can be done to your party and makes each playthrough of the game from player to player feel very unique and interesting, while also allowing for a whole lot of strategy potential. There is no end all be all top strategy in this game and if you play your cards right in any way, anyone can succeed. All of this culminating to an experience that feels deeply personal not to mention the many different ways you can go about collecting your party members. Visually the game is a spectacle no matter where in the game you are and when you aren't strategizing in battle you're marveling at the beautiful landscape or architecture or lighting or color palette around you.
Play this game.
