Looks like Octopath Traveler fever is hitting the world! A look at the Switch eShop in both Japan and the United States shows that Octopath Traveler is currently sitting pretty in the #1 position, beating out heavy-hitters like Minecraft and Captain Toad: Treasure Tracker. Let's hope the rest of the world follows along!
UPDATE - Looks like the game has hit #1 in Australia as well! Thanks to @RetroGameTrip for the heads up!
