People will always nitpick to disagree on a person's favored game.
And that's all it is.
Sometimes I wonder if it doesn't all come down to a certain amount of elitism in a genre where it isn't required to have it because of how broad and malleable it is.
Just my opinion, but I think it's the perfectly natural human tendency to think the intensity of our own personal experiences means we're completely correct, and that anybody else who differs from us just doesn't grasp reality.
