I'm certain these brands advertise they have quality, but I think they fall far short of the competition constantly. Nintendo? Disney? Apple? When I think of their actual quality compared to the best in the business you are talking B- quality.
Sure you never get a C or a D like when I get a random Android phone for $100, but you are never going to get a Baulders Gate 3 from Nintendo.
Although now that you mention it, all of these brands have total fanatics that border on cult worship. I wonder if this is natural, or some unethical psychology their marketing departments use.
