the game sold almost the same of usual remakes. And when you look how its campaign was small (june to november, just 6 months) and how the game reuse lot of props of past games and add nothing new aside from some real low cost graphics, the game didnt costed a writter, lot of work of game designers, really low cost on 3d designers etc. Its estimated that it was the most fast developed and the game with the lowest cost of the franchise(having even a 1/5 of the cost of usual games) and selling this much make it the most probable lucrative game in franchise
Masuda is a genius, he should get a promotion next game
