Japanese Earthbound/Mother fans haven’t seen a new game in its lovable series since the release of Mother 3 in 2006, so when one fan tweeted creator Shigesato Itoi about a Mother 4, he was met with a curt reply of “Impossible.”
You do have to keep in mind that Mother 3 suffered from an overly long development cycle. It was initially slated as a 3D RPG on the N64, dubbed Earthbound 64 in the West before being canceled in 1999. It took seven years to resurrect the game in 2D form on the GBA. Meanwhile, North America and Europe have yet to see it officially appear stateside, though the recent announcement regarding Earthbound coming to the Wii U Virtual Console does stir up some hope.
Considering how Mother 3 throws you for a crazy loop by the end, it’d be a dark way to end the series. Even so, fans have been at it with an unofficial Mother 4 for several years now, so perhaps some solace can be found there.
And as much as I feel for my Japanese brethren, us North Americans need Mother 3 before we even think about a Mother 4.
