@gamingonlinux I still don't understand why Valve doesn't have a 'Partially Playable' rating for stuff like this.
the gulf between "doesn't work at all" (implied by 'Unsupported') and "all modes of the game work" is vast.
that and their docs don't actually specify 'fully functional' for Playable (it's implied by the definition of Verified and their examples of 'Playable' issues), tbf, which would lead to this kind of inconsistency from interpretation.
