Core MechanicRoll 2d6 plus one of three attributes (Wit, Grit, Strangeness) plus a relevant skill and try to meet or beat a Target Number. Combat is an opposed roll. Beat the defender by 5 or more for a critical hit and double damage. Two resources then shadow every shift: Sanity drops when the supernatural presses on your mind, and Absurdity climbs as you lean into it. You spend Absurdity to reroll a failure, shrug off a point of Sanity loss, or take the higher of two rolls.Players roll a pool of 1–3 d6s against a target difficulty (4 for easy, 5 for average, 6 for hard). Every challenge starts with 1 die: add a second if the challenge matches the character's stat (Agile, Brawny, or Crafty), and a third if their role applies (The Veteran, Rookie, Medic, Gizmo, Detective, or Weirdo). Success means at least one die meets or beats the difficulty. Players spend luck tokens to invoke a perk and lower the difficulty by 1, and recover luck by letting their quirk cause a problem (raising the difficulty by 1). Grit tokens absorb failure consequences; a character who runs out of grit is removed from the scene. The referee never rolls dice during a challenge: they choose the stat and difficulty, then narrate the outcome. Extended challenges (chases, fights, infiltration) deplete a shared pool of effort tokens, one per success.

Best ForGroups who want low-barrier horror with a comedic streak for one-shots or short campaigns at a single weird location. It suits players who improvise from atmospheric prompts and lean into absurd moments instead of optimizing their characters.Groups who want a quick, comedic cosmic-horror RPG that pairs Baywatch-style melodrama with the Cthulhu Mythos. Tuned for pickup play and 2-4 hour sessions, with three tonal modes (Casual, Standard, Horror) that retune lethality without changing the core rules.
HighlightsSanity and Absurdity move in opposite directions, so the dark humor that raises Absurdity becomes a resource you spend to reroll failures or cancel Sanity loss. The Overnight Manager plays the gas station itself as the lead character, voicing its moods and the cryptic calls from its unseen Owners as a presence the table improvises around. Reaching 5 Absurdity unlocks Strange Abilities bought with advancement, once-per-session quirks the station leaves on you rather than powers you earn.Three difficulty targets and a 1–3 d6 dice pool make up the entire resolution system. Three tonal modes (Casual, Standard, Horror) adjust grit recovery rate, retuning the same rules from sitcom-style play to deadly survival horror without changing any mechanics. All heroes share a universal Slow Motion quirk: narrating a slow-motion moment recovers a luck token but raises the current challenge's difficulty. Adventure generator combines random Objective, Location, and Complication tables for pickup scenarios; also includes an Elder Gods & Cults table, a Monster Maker, and a mapped Sunset Hills setting.
ConsiderationsThe Overnight Manager sets every Target Number outside a few fixed tables and decides each Absurdity award, so difficulty and pacing rest on table judgment. Combat is deliberately thin: flat weapon damage, one primary and one minor action per turn, and only basic move-and-cover positioning rather than a tactical grid. Rituals, Strange Abilities, and backgrounds come as a handful of examples the book openly tells you to expand on yourself.Mechanically minimal: no advancement track beyond optional luck and grit cap increases, no gear lists, no tactical combat structure. Pacing assumes 2–4 hour sessions rather than multi-arc campaigns. Setting is anchored to Sunset Hills, California; running the game elsewhere requires reskinning the included cult, NPC, and location tables. Three difficulty values and a maximum 3-die pool give coarse resolution: granular skill differentiation is not the design.
