TradOC was just something that I thought would be more appropriate as a term because after talking with the writer of the blog, the article that he linked used the term differently(Basically hybrid storygame+trad game design mostly used in swedish game circles). I had a reddit post using it and my brain slipped calling it. And no, Neotrad isn't adapting the game to PbP or freeform RP but how people from those communities bring in those assumptions into TTRPG playTradOC? Is that neotrad/OC? Trad is a style of natural evolution to fit the needs of ttrpgs with a gm and other players interacting in a shared world. Neotrad is pretty much the evolution of adapting that game to a forum post where extreme asynchronous interaction provides room to shoehorn in a fanfic that others can interact with or ignore while doing the same themselves.
I think that the player trying to carry the disruption of neotrad to the table is more responsible than the setting for making it work. That responsibility comes in the form of a willingness to proactively carry all of the responsibilities pulled from the GM with their own actions and story building rather than just expecting everyone else to mold themselves to their neotrad story. No setting is capable of doing that for neotrad once neotrad takes the first step of changing the gm's role.
Calling neotrad disruptive to a game isn't quite right, after all it's a play assumption and all assumptions can be disruptive in the wrong group/place. A setting in an RPG for Neotrad players is instead is used as an assumption or a way for different players to have their desired arc or story to work together(literally or not). Almost like a validation in how 'this character fits' into the (potential) game world.
Also what I think a game that is most assuredly neotrad/TradOC, or at least designed with similar enough assumptions for the culture, and with a definite but flexible setting is Chuubo's Marvelous Wish-Granting Engine which I've heard is described as 'Play To Find Out How'
