Tough to say. Warcraft is certainly less popular than it was 10-15 years ago, but there's a heck of a lot more people playing D&D now, and a good chunk of them probably played some WoW back in the day.
Hard pass. They're great resources for other games and the production values are amazing, wonderful art, etc, but I cannot stand the 2d20 system, especially the rules heavy iteration Modiphius has put together for the Conan game.
Legend of Zelda, with the concurring time lines and eras presented as a ''multiverse''.
World of Final Fantasy. C'mon, at least for the bestiary of recurring monsters.
She-Ra/He-man, the new versions.
Dragon Age, if WotC was ever to lean hard into hard class/race restriction, that would be the way to do it.
For the ''adventure path'' side of things:
I think they would make a lot of bucks by selling the adventures from BG 1-2-ToB and IWD 1-2 as a compilation of 32 pages module in some kind of magazine or gazetteer.
I call dibs on Stoned Sean, DOH, but that means I'd start with the couch locked petrified condition. Honestly this sounds kind of fun, I'd play it for about 1-2 sessions before losing interest, but I'd play it for nostalgias sake.
