The game flopped pretty hard both in Japan and NA, but when it (hopefully) comes to the Switch, sales should be boosted considering the Switch has very little to the play for the upcoming year.
It's a shame the game needs these market conditions to be successful as it's a beautifully crafted game with great gameplay, visuals, music, story, etc. I also hope the US gets a physical release this time around. I think going digital only hurt it's sales in the West. People buying a throw back JRPG want a box damn it.
