PASSIVE INCOME
Resources that accrue without active play — rent collecting hourly, mines producing per tick, idle earnings accumulating offline — decoupling income from moment-to-moment attention.

Idle/incremental games (Cookie Clicker, AdVenture Capitalist) made passive accrual the entire genre, strategy games run per-turn income as their economic pulse, MMO garrison/mission systems (World of Warcraft's garrison tables) let armies earn while players sleep, and open-world property systems (Assassin's Creed II's villa, GTA businesses) deposit steady returns into chests. Designers use passive income for two distinct jobs: as pacing, per-tick income creates the strategy genre's fundamental rhythm (income rounds fund decision rounds, and economic growth compounds positional advantage); as retention, offline accrual converts absence into anticipation — returning to a full chest is a small homecoming gift that lowers the emotional cost of stepping away. Passive streams also reward setup play (build now, earn forever), which satisfies the investor fantasy that active looting never touches. Key decisions: the ratio of passive to active earning (when passive dominates, play becomes optional — the idle genre's deliberate joke; when negligible, the system is decoration), offline caps and decay (uncapped offline accrual makes not-playing optimal), and whether passive sources can be threatened, taxed, or raided — vulnerable income creates defense gameplay. Pitfall: passive income that outruns the game's sinks — compounding streams the economy can't drain eventually trivialize every price tag, and the moment money stops being scarce, every system priced in money stops generating decisions.
