When exactly do you think Hitler became popular? The moment he decided to attempt to take command of Germany, or after he had his population saluting him?
Maybe we should just wait and see how TLOU2 plays out before we agree or disagree if it ends up being popular. Who knows, maybe gamers are just waiting to get it on PS5.
It sold 4M+ on 3 days, there is no way you can say it isn't popular without putting like 99% as not popular (over 4000 titles on PS4, with like 40 selling over 5M TLOU2 already sold)
If it ends up hated in some years sure you can also say that, but there isn't anything right now that can put TLOU2 as not popular. Not even by your exaggeration like the "it isn't popular because it didn't sell like minecraft".
I never could have expected in backwards upside down world, flipping it to the exact opposite and suggesting it be judged right away and then possibly change minds later. Though, people deciding on something and forming a strong mindset first, and then changing it later, is much more realistic than simply waiting for everything before you make a decision at all. This is a rush type situation though so it's not like people have all the time in the world..
Hitler is also hated now, even by his own people. At least I would think that's safe to say, but you also suggested that it doesn't change that he was still popular. Which would likely mean that the implied TLOU2 popularity wouldn't change down the road either, even if it was hated, so..
I will say, that if anyone ever suggests that TLOU2 is literally Hitler, I certainly wouldn't agree with them.
