I wouldn't say Octopath Traveller is underappreciated. It got great reviews and was talked about a lot. Of course the hype has died down now since its been a while since the release, but its gearing up again thanks to the upcoming PC release (June 7th).
@carlosraruto: check your video settings. The games are old, and get finicky about changing resolutions. Despite having a setting for changing the game resolution, my experience is that you need to keep it set to its native 640x480, or it will crash trying to change resolutions between the VN and space sim portions. You may need to poke at your video card settings to ensure that it doesn't tamper with the resolution either. Creating a shortcut that allows you to run it in windowed mode can sometimes help as well.
While all pairings here are nice, it was especially exciting to see Kaede and Yuzu slowly becoming more close to each other with every chapter. Made me cry at certain point.
@GeneralJ I kinda get it both of their personalities and schools are the complete opposites of each other making for an interesting ship indeed. And I know misora is like Aruru's best friend but I just love her with tsukasa.
