How many meaningful choices a game asks from the player per minute, and whether their brain can keep up.
Decision density measures the rhythm of choice. A tactics game can be slow but dense because every move carries consequences. A walking sim can be sparse but still compelling because the choices are emotional, not tactical. Problems happen when density mismatches the fantasy: an action game that stops every 20 seconds for inventory math, or a strategy game with long stretches of autopilot. The right density depends on genre, audience, and pacing.
Example
Into the Breach has extremely high decision density because every turn exposes enemy intent and asks players to prevent city damage with limited actions. Vampire Survivors has low moment-to-moment input density but high upgrade-decision density every level-up. Persona balances long low-density social stretches against high-density dungeon and calendar planning.
Why it matters
Decision density is a useful diagnostic for why a game feels exhausting, empty, or perfectly paced. Designers who control it can create focus without overload and downtime without boredom.
