Second, regarding the jargon "high trust" (
@RareBreed @kenada )- I think I wrote this in the OP as an aside, but to make sure the point is driven home... all styles of play are valid. Different styles work for different tables at different times. In addition, I think that if you look at the history of TTRPGs holistically, you will see that different paradigms rise as a reaction to what came before. So while OSR came as a reaction to 3e (for example), 3e itself was a reaction to TSR-era D&D. That's why I think it's important to note that a lot of jargon is not neutral, but is both descriptive of a particular style of play favored by proponents of a style of play while also being an implicit critique of another style of play. That's why I don't find it particularly helpful to use a specific term of jargon generally to apply to other TTRPGs.
To use an easy example, people describe the early OD&D model as "Skilled Play." While this is a perfectly apt description of a style of play, it doesn't follow that other modes of play are "unskilled." And while I think that the term "high trust" has value in describing OSR and FKR, I would avoid, myself, call other models of play "low trust." Because that tends to end conversations, as it would put people that rightly enjoy 3e/PF1 (which was, and is, a successful game) in the position of using a pejorative to defend a game that they love. That's an issue with a lot of the jargon we see in our hobby- most of it was developed to critique some then-current style of gaming in order to elevate a different style of gaming.
Third, regarding some of the issues raised (
@EzekielRaiden ). I always say that some games work great in practice even if they are not appealing in theory (and, contrariwise, some things that sound great in theory don't work at all in practice). If you find it unbelievable that, say, OSR or FKR could possibly work, then you will probably have difficulty explaining why this style is so appealing to a decent segment of the population. Just because something doesn't work for you, doesn't mean that it doesn't work. People have their own preferences, and I think it's always best to play the things that you like!
