Hello there.
You are getting people details from people who like both types of games -
@hawkeyefan,
@Campbell,
@soviet, etc. - so it's possible that the problem isn't that you aren't getting details from people who like both types of games, but that you don't like what you are hearing once you do. Or maybe the problem is that you want someone who more obviously favors traditional games? I dunno.
I spend a lot of energy talking about and extolling the praises of narrative games not because I favor them over traditional games, but, rather, because this forum on the whole
strongly favors traditional games over against narrative games and people tend to grossly misrepresent such games. Most people know how traditional games work and then tend to favor those approaches heavily, if not solely, when discussing tabletop games. It's not like there is a shortage of advocates of traditional games here.
IME, that's not the case for narrative games, which sit do sit more on the margins. Many people know so little about them and there is a lot of misinformation and prejudice against them. They are relatively new, especially for people who come into the hobby from D&D and are enculturated by its play approaches. So a lot of my effort tends to be more about explaining how these narrative games work and defending them against people who think that they are dysfunctional, not real roleplaying, or badwrongfun.
But when one looks around this forum with even the tiniest bit of effort, and they will see me posting enthusiastically and starting threads about traditional and OSR games like Numenera/Cypher System, Shadow of the Demon Lord, Dolmenwood, Stars/Worlds Without Number, Index Card RPG, Fantasy AGE, Beyond the Wall and Other Adventures, Black Hack, etc. I also mostly play traditional games. I do have some mixed opinions about 5e, though I originally liked it. But I also think that its lustre has worn off for me for a variety of reasons. But all of my other posting about these games gets conveniently glossed over because I also decide to talk about narrative games that I also enjoy or also want them included in the conversation? That genuinely doesn't seem fair.
There are benefits to all these different games. I don't necessarily want to play narrative games all the time, and I do mostly play traditional games. Many games that I do like also tend to fall into a category that are sometimes called "Trindie Games," which tend to be traditional games that incorporate varying degrees of indie and narrative game elements: e.g., Fate, Cortex, Cypher System, Fabula Ultima, etc.
