A star chart of glowing constellations woven from threads of an unrolled scroll

The median SagaBound saga is 13 turns long, the average is 60, one saga in eight passes 100 turns, and the longest active saga has run for 2,408 turns. Those numbers come from all 1,982 real campaigns on SagaBound as of July 23, 2026, with internal accounts excluded, and as far as we can tell they are the first published turn-length figures for an AI-driven tabletop RPG. This post shares the distribution, what people play, and exactly how we counted.

The shape of play: a short head and a very long tail

A turn is one full exchange: the player acts, the Dungeon Master narrates the outcome, and the game state updates. Counting every saga where at least one turn was taken, half of all sagas end within 13 turns. That is the taste: a scene or two, an evening at most. But play does not thin out evenly from there, and the averages hide the story. The mean is 60 turns, nearly five times the median, because a substantial minority of players settle in and simply do not stop.

The percentile view says the same thing: the 75th percentile saga is 47 turns, the 90th is 134, and the 99th is just over 810. Thirteen sagas have crossed 1,000 turns. For scale, a 1,000-turn saga at a normal reading and playing pace represents something like 40 to 80 hours in one continuous story with one continuous cast.

Why the tail is the whole engineering problem

A 13-turn story fits comfortably inside a modern model's context window. A 134-turn story does not, and a 2,408-turn story is not even close: the raw transcript would be dozens of times larger than what any narrator model can read at once. Every saga past roughly turn 100 is running entirely on the game's memory systems, the rolling summary, meaning-based recall, and the codex, rather than on the model's ability to see the whole history. One saga in eight lives in that regime today, and those are exactly the players most invested in their stories. That is why memory work dominates our changelog, and how those layers work is covered in the memory and codex guide.

What people play

Epic fantasy is the genre four players in ten choose, which will surprise nobody who has shelved a tabletop RPG collection. The distribution after that is flatter than we expected, and the depth numbers hold a genuine surprise: the niche genres run longest. Westerns and mecha sagas average roughly 84 turns each, more than any other genre and well above fantasy's 72, though both are small samples and we hold that conclusion loosely.

Modes: early days for the new ways to play

Adventure, the classic mode with combat, health, and quests, accounts for 95.5 percent of active sagas, which is expected since it was the only mode for most of SagaBound's life. Storyteller mode, the pure-narrative option, launched on July 8 and already carries 87 sagas, 4.4 percent of the total, in its first two weeks. Tabletop mode entered early access for Paragon members on July 16 and has 2 active sagas as of this snapshot, a sample far too small to say anything about, so we will not. When Tabletop has real numbers, including how often Face Death actually kills a character, that gets its own post.

Methodology, in full

  • Snapshot date: July 23, 2026. Numbers are frozen as of that date and this post says so rather than silently drifting.
  • What counts as a saga: a save file where at least one turn was committed. 479 zero-turn saves (character creation started, never played) were excluded from a raw pool of 2,461.
  • What counts as a turn: one committed player action and its narrated outcome. Retries, edits, and questions to the DM do not increment the count.
  • Who is excluded: 300 internal accounts used to seed community content, plus their saves. No real player data is excluded.
  • What this cannot see: sagas deleted before the snapshot, time spent reading versus playing, and anything about individual players. Every figure above is an aggregate; no per-player data leaves the aggregation script.
  • The 1,982 sagas were played by 1,445 distinct players across 141 different worlds.
