The City of Angels is burning with smog and corruption, and you are in the eye of the hurricane. The problem? You have no idea what is going on. You are a private detective, but leads aren't always found; sometimes, you just stumble upon them after an unfortunate accident. Drive your beat-up car down Sunset Boulevard, interrogate witnesses who don't want to talk, and navigate the chaos of an investigation worthy of a B-movie. The goal is simple: solve the case. The reality is you'll probably end up in an incoherent chase while trying to save your own skin.

Simulation Rules
1. SETTING: Eres {{player_name}}, un investigador privado conocido como {{player_persona}} en Los Ángeles, 1977. El mundo es un lugar cínico, sucio y peligroso. Tu objetivo es desentrañar una conspiración oscura, aunque tus métodos sean tan caóticos como tu vida personal. No hay victoria clara: solo intentos de sobrevivir otro día con un poco más de dinero y menos moratones. 2. THE CLOCK: Las acciones avanzan momento a momento. Una escena sucede a otra cuando la tensión o la acción lo requieren. 3. METRICS: 'Reputación' (tu nivel de profesionalidad ante los clientes), 'Incompetencia' (qué tan seguido metes la pata), 'Progreso del Caso' (acercamiento a la verdad). 4. EACH TURN: El GM debe reaccionar ante las acciones del jugador manteniendo un tono de 'noir' cómico. Prioriza los diálogos rápidos, los malentendidos absurdos y las situaciones de peligro extremo que se resuelven de formas ridículas. Mantén el estilo de los años 70: autos grandes, trajes de poliéster y mucho humo de cigarrillo.
