Why you guys think anyone else should be saying anything about Abandoned is beyond me. They shouldnt, and they aren't going to.
Look we are already past the point where the silence from Sony will lead to a serious damage of Sony's reputation, if it turns out really just to be an indie who is clearly lying.
So they have any possible motivation to say something to stop this, but they don't. Sony knows very well how wild the thing has already become, proven by Shu's suspicious tweets.
But okay let's say Sony is stupid and stay silent, why in the world should Kojima-san stay silent?
Regardless of what he tweets, half of the responses in these tweets refer to either Abandoned or even address him as Hasan. Imagine you are in his position, you have a reputation of a world famous and respected game designer, would you be okay, if many people call you by the name of a obvious fraud on the internet? Surely you would also get tired and at least make one simple tweet, that you are not related to them, but instead Kojima says nothing. Quite the opposite, he makes tweets where he even sparks the flames. Do you think Kojima is so stupid to not realize how some of his tweets could be connected to Silent Hill?
So it is not team real, but you who are delusional and probably don't want it to be true, becasue you dream of your exclusive Kojima Xbox game...
