The same reason all normies love Breaking Bad and other shows similar. They all watched youtube videos explaining to them how X media is "an artistic masterpiece" and now want to pretend that they get it and are super smart for it, but are just following a trend. We had like 2 decades of people talking about Silent Hill 2 being a masterpiece and like 9 million youtube breakdowns of the story, themes, etc.
Doobson is a normie in denial, he thinks he's really interesting and cool, but he likes what people tell him to like, he believes what people tell him to believe, so "Silent Hill 2 is teh gr8est game ever" is just the latest code loaded into his Coomer NPC brain along with all the other normies.
I'm sure when the next good game from 20 years ago gets cash grab re-released for 60 bucks we'll see him telling us about how important and deep it is too.
