I mean, I've been creepily stalking his anti-saturn posts for a few years...and I recall him talking about a lack of "triple A" games or something like that. And that's fair. Most people like those kind of games, those are the kind of games that sell consoles, and the saturn didn't have many of those kinds of games (in the US?). So why do all of these people like the saturn now?
Well, the lack of games by major publishers with higher development and marketing budgets can definitely spike the popularity of a console after it's long discontinued. Generally those so called triple A games are designed to appeal to a broad audience, hence they don't offer much originality and are mostly carbon copies to corresponding blockbusters on other consoles. So it's the smaller, more unusual, more obscure stuff, that forms a console's appeal during its afterlife. 2D arcade games definitely fit that description now, where 2D sprites only exist as an exception.
Considering that the Saturn was from the 5th generation, i.e. the beginning of polygon based 3D gaming, I'd add that those former blockbusters often don't age too well, because their appeal was based on the use of state of the art visuals during pioneering days of 3D and will loose any comparison with successors from generations that followed. That's not the case with 2D sprite-based games, which reached their heyday during that time. This would suggest, that a 5th gen library with
less 3D "blockbusters", but more 2D games, will also age better.
When you think of the Saturn, then think of van Gogh, who never sold during his lifetime, because he didn't do, eh, "tripple A" paintings. Long after his death, he's considered tripple A for collectors and art historians alike, while from time to time someone will call him overrated.
