You'd really need to very thoroughly re-work Dark*Matter's lore because it's er... messed up and not in a good way, and in, accidentally, a very politically relevant way today, because the current government of the US got elected in part because of very similar conspiracy theories and itself perpetuates some of those conspiracy theories (specifically the FEMA and CDC ones among others). It's also pretty straightforwardly real-world racist in ways that were messed up in 1998 and are only more messed-up today. I won't derail but I went into some detail and specifics a couple of years ago here.
I was looking back at the Dark Matter campaign awhile ago and felt the same way. The fun has been sucked out of conspiracy theories.
Even in the 1990s, Dark*Matter was pretty off-beam because it essentially "flipped the script" on stuff like the X-Files, without saying it or making it obvious by doing the following:
1) Has very dodgy far-right attitudes to less secretive government agencies - it's really mad with the ATF, for example (even though it admits it's not a conspiracy!). FEMA is 100% as evil as the wildest far-right conspiracies would have, literally a fascist...
There are significant other setting issues beyond what I outline there which mean the entire setup is a weak one for a conspiracy setting/game.
I do think a conspiracy-oriented game like that could be worth having in the mix, but that one needs a top-to-bottom re-write and frankly would need to make up new conspiracies (or dig up really out-there ones) rather than using old ones.
TLDR: "Amazons of the Gynarchy" lol.
Re: what game I'd like to see come back, honestly, this is perhaps cheating slightly (but I think technically not because there genuinely isn't a 2nd edition of it), but I feel like
Cyberpunk 2020 didn't get, like finished, but was left hanging. So to me it feels like it wasn't that short-lived or lost, but it was imho weirdly abandoned.
Cybergeneration, V3.0 and RED are clearly different games with very different settings and ideas (much as RED might pretend otherwise). I don't know the exact story of what happened but 2020 was exactly 66% of the way through a massive world-changing story-arc, and we never got the last 33%. Even though the book before it directly promises it's on the way, and AFAIK, RTG didn't have some kind of crisis that prevented them from putting out the third book (correct me if I'm wrong). They just... didn't. Not sure if Maximum Mike has ever really explained why (and RED's backstory conflicts with stuff from even those two books so doesn't help a lot).
Also you can feel in the last few supplements that Mike had just checked out on 2020. But he had a lot of other people excited to work on the game/setting, so I'm not sure why he couldn't just let that continue (given he'd always only done a certain amount of the work on 2020).
Dungeon World was on this list for me for a long time, but I feel like it no longer is, as the ground it covers is now far more than adequately covered (and not by the upcoming DW2E which is something else entirely).
