I don't think it's only Nintendo fans. But I think they are the worst.
In comparison, right now Microsoft is really screwing up on the first party titles. But most MS fans are like "yeah I know, it's bad, I hope it gets better, they should do that and this"
Nintendo fans are like "No, you are wrong, why are you trolling? If you don't like it don't buy it! Go buy a PS4!" It's like talking to 12 year olds, but I know they are older. Seriously people, try to have a conversation. We are consumers too, we have opinions, I own every piece of hardware Nintendo made, I have expectations about what a good system is. The Switch doesn't meet them. I have a right to voice them. I'll probably own the damn thing in a few years, I expect it to have a lot of good games when I purchase it, and I don't believe that will happen if people lie there and take whatever Nintendo wants to give them.
It's not a console war or trying to put Nintendo down, it's about thinking Nintendo could and should do better. And the problem is that a lot of people think that Nintendo is always fine whatever they do, that they are always above criticism.
An I saw a lot of those people just give up with the switch. Finally it was the last straw, that's why there is so much division and arguments right now.
But many of them are still defending it despite not really liking it, it's funny, there was one guy, defending the system like it was perfect, and then he said to me "anyway, whatever, I don't plan on buying it, there is that and this that I don't like about it"
WTF, it's like I can't criticize it, but you can. What is wrong in those people's head?
