"because if a product is good people will give their hard-earned money to get it."
Sure, dude, like the guy there said, following yoyr logic, Justin Bieber should be best musician of all time. Those Transformers movies? Man, these are the real cinema classics.
Also, Devil's Third didn't have good sales?
Dude, Devil's Third in Japan was released on Amazon.jp. In the US it's happening the same thing, the game is getting a very limited release. Let alone the fact the game had ZERO marketing. Nintendo didn't bring the game to any event, didn't show it on any Directs and TV commercials? Not a chance.
By the way, the is completely sold out. In other words, this shows people are in fact interested in game. At least, more than what Nintendo thought they would be.
So the game didn't sell well? NO SHIT, SHERLOCK!
Also, just go to miiverse and see what people are saying about the game. Everyone there is giving positive impressions. If people are not enjoying the game, why the heck everyone who is actually playing it is saying the game is good?
