Dragonquest (1st, 2nd or 3rd editions)
Powers & Perils
Lords of Creation
I've made the mistake of claiming all of those are dead at various points in the last five years. and got vigorously corrected with enough evidence that I'm willing to believe they still have their player bases. Heck, I'd play LoC myself now and then just for the sheer gonzo factor if I still had a copy.
Villains & Vigilantes (seems to be getting new content on the FGU site)
That's a bit of an illusion. You can see when various products were added to DTRPG, and the most recent thing (To Dream, To Conquer, To Rule - which is also part of the Giant #3 compilation on the "new" section of the FGU site and has been in preorder limbo for quite a while) went up back in 2021. Prior to that the most recent item is from 2018.
FGU has released quite a few things after the initial stop at the end of the 80s, but they've showed up in several clumps. IIRC there were a few (including some unseen stuff written in the 80s) in the Oughts, a bigger clump around 2012-2013 (when Bizar and Dee/Herman were court over the rights), and semi-steady output throughout 2016-2018.
Monkey House Games has the rights to the rules (but not the V&V trademark, that's used with Bizar's permission) and a few of the old adventures, but their own output has been pretty light - three new adventures, two free mini-adventures, Mighty Protectors/V&V 3.0, a miscellany of other play aids and older material from the FGU days, and most recently a big WW2 sourcebook in 2021.
Accurate to say V&V (in any edition) has had half a decade since any new releases from either publisher, and there's nothing in the works that I know of.
That said, yeah, it's definitely not dead in terms of fan base online, and the surviving members of my old school days still play it once or twice a year for nostalgia's sake.
