@presgas I wish I had counted sessions overall!
Phandalin: 12 sessions
Lost City: 24 sessions
Princes: unknown (maybe… six?)
Glitchworld: A little over a dozen, maybe 18 or so
Curse of Strahd: The one campaign I have the least idea of how long it went. I didn't count at all. We were playing every day (which I really loved doing). I would guess thirty or so sessions. We also did Deep Carbon Observatory, there's a place on the Barovia map where it fits perfectly.
Corsair Council: Maybe a dozen or so sessions, maybe ten or so.
Chult: Exactly 100 sessions!
Boatmode: 138 (except also five sessions of
#gothmode, which, now are part of
#boatmode )
Bladen Faller: 2 sessions.
And at least three one shots
I wanna do a Marvel-style "Legacy numbering" at some point.
We also had the "1001 Nights Off" side campaign where we were doing story games set in and near Hawa (in the same continuity as our D&D game). We did Microscope, Chtulhu Dark, Dogs in the Vineyard…
Oh yeah, we also did I don't know how many sessions in the ISotU/KotB mashup world that came out a few years back!
