Tokyo Mirage Sessions #FE Encore is coming to the Switch, and this version of the game is based on the Western localization of Tokyo Mirage Sessions #FE. That Western version had some toned-down content compared to the Japanese release, which some saw as censorship.
When Nintendo announced Tokyo Mirage Sessions #FE Encore, they failed to say that it would be based on the Western version of Tokyo Mirage Sessions #FE, which had numerous fans feeling mislead. Those who preordered were expecting the Japanese version of the Switch port to be the same content-wise as the original Japanese launch. Nintendo has since apologized for the issue, and is issuing refunds.
All this fuss surrounding the game's launch has had an interesting side effect. Over on the Amazon Japan Wii U charts, Tokyo Mirage Sessions #FE has shot straight up to the #1 position. It looks like people want to make sure they lock in a purchase of the original Japanese release, rather than go with the Switch port!
