If anyone is enraged, then that person needs anger management classes.
Even if we grant that Gamefreak lied, and even if we assume it was done with particular malice, there is still no reason to be enraged, because the lie did not in any way negatively impact you. The game was available for all to see well before release, and relevant facts detailed. By the time the game came out, they had ample opportunity to see what the game was like. If you think it's a low quality product, then the appropriate response is to not purchase it. If you feel like you need to explain why you don't want to buy it, then I'm not going to tell you how you should spend your time.
But to be mad is to imply that Gamefreak somehow cheated you out of something. That they had some duty to you that they did not properly fill. In other words, that you were entitled to something.
I'm not purchasing it, that doesn't affect me, don't worry.
But yeah, when a company lies to consumers they have the right to be enraged because it may actually be affecting them, if people did actually believe what they said despite what they saw in the trailers they have the right to be mad.
GameFreak doesn't owe anyone anything, but people also doesn't owe GameFreak anything either.
People should be free to call out everything they are unhappy about a product, and they are doing so, that's it.
I specifically said that people can explain the reasons why they don't like a particular product. There's a difference between calling something out, and being enraged.
And why would anyone have any reason to be enraged? If people believed what was said despite the trailers and all the footage that was put out of the game, then those people are simply stupid. This is not a case like others where developers intentionally hid flaws, showed games running on other hardware, used pre-rendered videos instead of actual footage, or anything of the sort. There were many hours of gameplay footage revealed before the game came out, the review embargo was lifted several days before the game came out.
Even if Game Freak lied in an interview, you have to look at the sum total of all the information given about the game. Say I told a woman that she should marry me because I'm rich. I'm actually broke. Right after I propose the marriage I give her a completely accurate, detailed, and easy to understand history of my finances, before she has any obligation to take any action. She marries me anyway. Is it rational for her to then be enraged because she was tricked into marrying me? Even if she doesn't marry me, should she be enraged because of the lie? Was there actually any deception if she was given all the information she needed to make an informed decision?
To repeat and clarify, I believe to be enraged, someone has to have done something that in some way causes legitimate harm to another. What legitimate harm has been done by Game Freak that would entitle anyone to be enraged, or even just garden variety angry?
