I just disagree that it's the majority because most people I currently play with, and have played with over the decades, have tried other games. All of them at least know of the existence of other games, most enough to form an opinion. I don't have to drive a Cybertruck to know it's not a vehicle I would ever want to own even though I've never driven on. I happen to like smaller (preferably sporty) cars.
Again, this comes back to that hypothetical "better" game. Given infinite choices, infinite games, there will always be something better. It's also meaningless..
