• ask any old-timer fanfiction writer about this. “fan work” as a whole–including mods–is a gigantic gray space in current copyright law and IP holders are almost certainly within their technical legal rights to prohibit any works like Revolution on a blanket basis. the current arrangement where most rightsholders look the other way and/or accept the existence of such fan works is a largely informal one, and there’s nothing codifying it being that way. it could arbitrarily change (or just be fucked up by a court case) at pretty much any time–and, indeed, occasionally rightsholders still do try and enforce their IP quite aggressively.

        Steam has a workshop specifically for people to release mods on to. I understand you might be somehow new to the concept of mods, even though they’ve been a thing for 30-40 years now, but that’s what the Portal mod is - a mod.

        It’s even tagged as “mod” on the steam page.

        It’s not a recreation of the original game.
