yeah it might be more useful to think of Skilled Play as moving on and being inclusive from more than that, even if not everyone likes the solutions equally a lot of our current mechanics were developed inter-textually with this idea of skilled play, to further develop the concept and move past the problems of it as we've identified in this thread.
I guess we could move to a NSP (Neo-Skilled-Play) terminology but its like Rob discussed in the OSR thread, he doesn't like the boundaries presented by enclosing him and his friends within that particular school of thought with those particular elements presented, because they've continued to develop and tinker with a clear lineage from their earlier work, so the purity might be problematic from a design standpoint-- instead of taking us away from skilled play, elements like character mechanics that provide information and SOP level details could be read as an improvement within the Skilled Play context. This would also be beneficial because it would allow us to view and design around those mechanics to avoid damaging the Skilled Play component overall.
By and large, this seems to be a sticking point many of these threads return to, where the discussion is being perceived as in service to and policed by the terminology, rather than vice versa. Questioning these accepted bounds is rendered difficult, because they're perceived to be definitive (and therefore intrinsically truthful) rather than descriptive (and therefore subject to commentary, criticism, and debate.) I'd liken it to notions of the 'canon' in literature criticism, and how there are accepted interpretations and value judgement that can cause the medium to stagnate until the hold can be broken and the excluded works and interpretations 'break in.'
