Why are people so invested in "proving" that D&D isn't a great game or even a good game? That it's only popular because it's popular. It's baffling. Look there are things I don't like about 5e - the level of magic in the game is through the roof for me and I would very much like to strip out about 75% of the spells (which, incidentally, I did) - but, I've been playing it once or twice weekly for ten years. It's obviously something I enjoy doing. Not because of "marketing" or "influencers" but, shock and surprise, it's a pretty good game that runs pretty smoothly.
Funny thing is, I just tried Warhammer Fantasy for the first time recently. Now, I did not like it. I did not enjoy it at all. But, that in no way is a reflection of the quality of the game. That's just me.
