Final Fantasy XV will have to sell 10 million copies to break even, according to director Hajime Tabata.
Tabata made the claim in a press conference on the weekend.
Square Enix has made a substantial (though undisclosed) investment in the action RPG, which began development in 2006, when it was to be titled Final Fantasy Versus XIII.
In addition to the game, the studio is also producing an anime series and a CGI animated movie to flesh out its setting and story.
To put the required sales figure in perspective, in the Final Fantasy franchise, only VII has sold that well; 10 million copies is the realm of Super Mario 64, and twice as many copies as fellow Japanese open-world action game Metal Gear Solid V has sold to date.
Final Fantasy XV releases September 30th, 2016, on PS4 and Xbox One.
