@Giganova8 given what momo did with BOIII it's safe to say that cod modders are really fucking retarded.
(Context: he patreon paywalled his mod, then when his other project got a C&D he did a "if I can't have it nobody can" and took it down, with a nasty license that's proprietary as all fuck and anyone forking his code being met with him chimping out and threatening legal action).
In other words many of them (not all) deserve to end up like SNES emulator developers.
That would be cutting a deal with some level of official publishing though. I'm talking about the self-important retards who think like the guy @PurpCat posted.
