I'm sure you can see into people's souls too and work out what they think, right? Saying "people who backed the game must love it because they are deluded" is just as pointless as saying "people who criticise the game are just trolling". Neither have any basis in logic or reality.
There were reviews also up within minutes of people giving the game a zero, for example because it has "old graphics" or whatever else. There's a lot of stupid people saying nonsensical things from every spectrum. Again, it's funny that you're doing exactly what the OP is cautioning against - assuming everybody is a troll.
And here again, a backer rushing to the defense of their "precious." There's a reason that Steam is forcing the people on there to disclose that they have been PAID for their opinions. Maybe you aren't aware of whats called astroturfing? Hiring shills to pretend to be real customers and give fake reviews, and now also to post in social media sites in order to control opinions. I'm not going to argue with you because I really don't care, I know how things work now I've seen many times, and the gaming industry can get away with it easily because their main demographic is children.
