Campaign Length

I'm looking at campaign options for when the current situation winds down and we can begin gathering again. This means I'm poring through old binders and spirals looking at what I've done before and I thought I would share some numbers from the last 20 years:

• 3E Seas of Kalamar campaign - 34 sessions
  This was set in Kalamar and combined the original Freeport trilogy (which we finished) and the Savage Tide adventure path from Dungeon magazine (which we did not). This was my last 3rd edition campaign.

• 3E Scarred Lands campaign - no fancy name here - 54 sessions
  This was set on Ghelspad in the Scarred Lands and covered quite a bit of territory from Vesh and Mithril out to the Blood Sea and eventually spent a bunch of time in the city of Amalthea. I used a lot of Necromancer Games and Goodman Games modules in this one - Seroent Amphora, The Wizard's Amulet, Idylls of the Rat King, The Dragonfiend Pact, Tomb of Abysthor, Bloody Jack's Gold, White Plume Mountain, The Blackguard's Revenge, and Iron Crypt of the Heretics, where the whole thing ended in a TPK around 11th level.

• 4E Return to the Ruins of Adventure - 30 sessions
  Yes it's Phlan,from the AD&D Ruins of Adventure module and the Pool of Radiance computer game! It was a lot of fun.

• 4E Savage Swords of Impiltur - 30 sessions
  Most of this campaign was following the Red Hand of Doom mega-adventure from D&D 3.5. I had heard good things about it, never ran it in 3E, so I converted it to 4th and we got very close to finishing it but not quite. 

• 4E Temple of Elemental Evil - 11 sessions
  This was a side campaign I ran for the boys in between other games. It didn;t last as long as the others but they did explore Hommlett, cleared ourt the Moathouse, and cleared the ruins of the Temple. We just didn't dive into the dungeon beneath as other things took priority.

• Pathfinder  Wrath of the Righteous - 38 sessions
  I've written about it, particularly why it ended, elsewhere on the blog but it was fun most of the time. We've discussed picking it up with PF2E but we all want more experience with that system before we try to go high-level with it. 

• 5E Cormyr Classics - 21 sessions so far
  This is set in Cormyr and has included conversions of Keep on the Borderlands and Isle of Dread and is ongoing though it's been a few months since we last played.

I ran an earlier 3E campaign set in Greyhawk but I didn't keep notes like I did with later games. It ended in a self-inflicted TPK in the middle of the crater ridge mines in Return to the Temple of Elemental Evil. There have been various other one-off, short runs, and faded campaigns with other games over the years but I'd say these are the "core", longer-running games I've had.

Seems like 30-50 sessions is my sweet spot - should I consider this in planning a campaign? No more epic adventure path type runs? Maybe shorter ones? Or should I go for it - buckle down and aim for a full level 1-20 progression, even if it takes 100+ sessions?

Something to think about.
