Mother 4

Reggie Fils-Aimé says “don’t hold your breath” for more ‘Earthbound’

There's apparently only a "relatively small group of fans that desperately want to see 'Mother 3' or something next in the 'Earthbound' series"

Fan-made ‘Mother 4’ is revealed with a gorgeous first trailer

"Nintendo only seems to go after remakes of existing games, or controversial fan games"
