In general yes, but there are some good guests that were there. For example, in case of nutrition, Dr. Layne Norton called him out on having a guy that was talking nonsense on the podcast and then they got in touch with Layne and had him on the podcast where he explained many of the misinformation about nutrition currently in wild.
Ofc, it is always fun to play it, but you are not watching just anyone that plays a game, but the best there are in it. It's always interesting to watch how the "pros" do it, even for a little while. It's not that different than watching sports...
And not every game will be popular, just like not every sport is, but no one can't deny that a game like league of legends is not getting hugely popular, and tournament prizes are going insane.
It's just that for now most people still see games as something you do "just for fun" not something you can live ofo, but that is changing as we see in this example.
