Among D&D, definitely Dragonlance, given the ongoing generational campaign that’s been going on for more than 25 years of real time and a century of Krynn time (on and off in both cases) across systems from 2nd Edition to 5th Edition. The main DM started it in middle school (using photocopies of my 1st Edition Dragonlance Adventures hardcover along with his 2nd Edition books) and he’s now DMing his own young son in it. I and others have played my own grandchildren (and the children and grandchildren of my friends) in sessions and mini-campaigns over the years — the group of us who played in high school only ever play that when together and some among us have run parts of it at different colleges, with adult friends, and in Afghanistan and Iraq.
(I say “in D&D” because, even with all that, I’ve played and ran more sessions over the past fifteen years of a hyper-connected Rifts/Heroes Unlimited/Palladium Fantasy multiversal supercampaign)
