A lot of people don't get what the OP is saying, if they even read the first page lol, but I actually did and I don't really agree tbh. I don't think the higher difficulty levels change the gameplay loop to such a degree that a lot of people would change their opinion in mass like that. I think the same people who don't care much for the gameplay itself wouldn't all of sudden care about it, and those that don't think it's great will think it's great just because it's harder. It's just not the highlight of these types of games for a lot of people, and honestly, that's okay. It's pretty basic overall, and there's nothing wrong with that.
