Data queried September 29, 2026. We will rerun this page once 25 campaigns have concluded, which is when campaign lifespans become measurable.
Short version: four campaigns here have finished. They ran 7, 10, 32 and 42 sessions. Everything else is still going, so every other number on this page is a floor rather than a length: the median campaign has reached 6 sessions over 6 months, at a pace of 1.7 sessions a month.
This data cannot tell you, because 74 percent of these campaigns played within the last 60 days and have not ended. What they have reached so far is a median of 6 sessions and about 6 months. A quarter are past 11 sessions. The oldest has run 55 sessions across more than six years.
People say campaigns die before session five. Four campaigns here are marked complete, and the shortest ran 7 sessions. Four is too few to prove anything either way. Five campaigns with five or fewer sessions have gone quiet for more than 60 days and none has been marked finished, so we cannot tell whether those ended or paused.
Tables organized enough to schedule, record and publish their games are the least likely to fizzle early. Everything here is evidence about committed tables.
Six, at the median, with 46 percent sitting at five or fewer and a quarter past 11. The top tenth are past 34 and the highest is 55. Campaigns enter this data on their first recorded session, so the bottom of that range keeps refilling with campaigns that started last month, so these counts skew younger than the tables themselves.
Among campaigns with three or more sessions and more than a month of history, the median pace is 1.7 sessions a month. Weekly is the aspiration. Put that beside the session-length data and the median table is playing about five hours of D&D a month, which is one evening every two weeks and the reason campaigns measured in sessions look so slow measured in years.
55 sessions across just over six years, and it has not recorded one in four months. Two more run 51 sessions across about three years and 45 across eighteen months, both still playing. Among campaigns with three or more sessions the median span is 6 months so far and the 75th percentile is past 12, so the ones that get going keep going for a long time.
7, 10, 32 and 42 sessions, a median of 21. All four were imported rather than recorded from session one, which means a GM typed those dates in by hand: the session counts are solid, the calendar spans of six weeks to a year are recollection, and we do not read a pace from them. A campaign somebody imported after the fact is also a campaign somebody cared enough to keep, so treat these four as a sketch of a finished campaign rather than the average one.
Three of them stopped after one or two sessions and have recorded nothing in five months. The fourth is the six-year, 55-session one, quiet for 123 days. Ask instead for campaigns that ran more than 90 days before falling silent and only that last one qualifies, because the ones that stop early stop before they have a span to measure. Among everything still moving, the median gap since the last session is 25 days and 90 percent have played inside the last 105.

| Still active (played in last 60 days) | 74 percent |
| Marked complete | 4: 7, 10, 32 and 42 sessions; median 21 (spans are GM-entered on import, roughly six weeks to a year) |
| Quiet more than 90 days, not marked complete | 4, at 123, 149, 156 and 159 days; three of them stopped after one or two sessions |
| Days since last session, still-running campaigns | median 25; 90th percentile 105; max 159 |
| Campaigns at or under 5 sessions that have gone quiet | 5; none marked finished |
| Sessions per campaign so far | median 6; 75th percentile 11; 90th 34; max 55 |
| Real pace | median 1.7 sessions per month |
| Span so far (3+ session campaigns) | median 6 months; 75th percentile 13 months |
| Longest campaign | 55 sessions across 6+ years; quiet for 123 days |
| Concluded at or before session 5 | 0 of the concluded campaigns |
Session counts and dates come from each campaign's recorded sessions; a campaign's span is first session date to last. Activity means any campaign touch in the last 60 days. Known confounds, in order of importance: most campaigns are still running, so every distribution here is censored (a floor, not a lifespan); the sample is self-selected committed tables on one recording platform; and some campaigns imported earlier history while others joined mid-campaign, so a span can start before the platform did or after the campaign did. Imported session dates are entered by the GM, not measured by us, so spans and pace that include them are only as good as the GM's memory; restricted to campaigns recorded on the platform from their first session, the median pace is about 2 sessions a month, which is the same every-other-week story. Test and demo campaigns are excluded. If you want a cut we didn't run, ask: hello@thread-fall.com and we'll run it.

There is no answer yet, because 74 percent of these campaigns played within the last 60 days and have not ended, so every number is a floor rather than a length. What they have reached so far is a median of 6 sessions and about 6 months of play, a quarter are past 11 sessions, and the oldest has run 55 sessions across more than six years.
The four campaigns in our data that their GMs marked complete ran 7, 10, 32 and 42 sessions, a median of 21. All four were imported with GM-entered dates, so we trust the session counts, not the calendar spans. Four is a small sample, so treat it as a first sketch.
Four, so far. Counting a campaign as stalled when it is not marked complete and has recorded no session in 90 days, four still-running campaigns qualify as of September 2026: three that stopped after one or two sessions and have recorded nothing in five months, plus a six-year campaign on a 123-day gap. Narrow that to campaigns which ran more than 90 days before falling silent and only the six-year one is left, because the campaigns that stop early stop before they have a span to measure.
There is no single average yet, because most campaigns in our data are still running. The typical campaign so far sits at 6 sessions and about 6 months of play, at a pace of roughly 1.7 sessions a month, and a quarter of them have already passed 11 sessions.
Every other week, roughly. Among campaigns with at least three sessions and more than a month of history, the median pace is 1.7 sessions per month. Weekly is the aspiration and every other week is what actually happens.
No campaign here has ended at or before session five. Four are marked complete and the shortest of them ran 7 sessions. Five campaigns with five or fewer sessions have gone quiet for more than 60 days without being marked finished, so the data cannot say whether those are over. Tables organized enough to schedule and record their games are the tables least likely to fizzle early, so treat this as evidence about committed tables, not all tables.
Years. The longest campaign in the data has 55 recorded sessions spanning just over six years of table dates, and it has not recorded one in four months. Two more run 51 sessions over about three years and 45 sessions over a year and a half, both still playing.
