The only dead franchise I've been holding a candle for years is Legacy of Kain.
I know the canceled 'Dead Sun' was basically an original story with the LoK name (and some elements) slapped onto it, but after learning more about it, I'm glad it got the axe. I never touched the 'Nosgoth' MOBA for various reasons, and even that's dead now, too.
But while Raziel's story was wrapped up as good as it could get in 'Defiance'... it's not really easy to make a legitimate sequel that finishes Kain's arc once and for all: The story got incredibly convoluted and you've pretty much locked out new players if you continue the game from the end of 'Defiance'. Yeah, the Soul Reaver games (plus Blood Omen 2 and Defiance) are on digital services, but Blood Omen is trapped in a legal nightmare (Silicon Knights and Dennis Dyack are lolcows in of themselves), so it's never been released to places like GOG or Steam, and probably never will until Dyack croaks or is finally committed to a mental institution.
The only way they can really do LoK now is to just do a hard, 'Tomb Raider'-esque reset on everything. And frankly, after 'Tomb Raider" and 'Rise of the Tomb Raider", I'm beginning to wonder if it's probably for the best that the LoK series is dead.
