Gambling
In-world casino-style minigames — dice, cards, roulette, cockfighting — that let players wager currency for a chance at more, purely as a diegetic activity separate from the main progression. Red Dead Redemption 2's poker and blackjack tables and The Witcher 3's Gwent (though Gwent grew into its own metagame) both use gambling to add flavor, immersion, and an optional currency sink or source. Designers use gambling minigames to flesh out a living world, to give players a low-stakes diversion between main content, and occasionally to double as a soft tutorial for probability and risk assessment. Key decisions: whether outcomes are truly random or can be influenced by skill (bluffing, card-counting opportunities), stakes scale relative to the main economy (gambling shouldn't trivially fund the whole game), and whether it's purely flavor or ties into any real progression. Pitfall: gambling systems tuned to be profitable enough become a degenerate strategy that overshadows intended progression — most implementations deliberately cap the exploitable upside.
