GTA V's stock market pairs with its assassination missions in the medium's best-known implementation (kill the CEO, short the stock — insider trading as mission design), Capitalism and business sims run full exchanges, EVE Online's player-driven markets support genuine securities behavior (speculation, cornering, fraud), sports management games trade players as appreciating assets, and tycoon designs use rival-share purchases as the hostile-takeover endgame. Designers simulate markets because they're engines for indirect play: a stock market converts the game's events into prices, so everything happening in the world (wars, scandals, your own missions) acquires a second meaning as trading information — and the player who acts on that information is playing the game's events themselves as an instrument, profiting from knowledge rather than labor. Markets also offer late-game wealth something to do (the portfolio is a sink that produces engagement rather than power inflation), teach financial literacy through consequence, and — in the GTA mode — let designers write missions whose reward is what you knew before everyone else, gaming's cleanest insider-trading fantasy. The simulation depth question is honest fakery versus real dynamics: scripted price responses to known events are legible and exploitable by design (the point of GTA's version), while emergent supply-demand markets (EVE) support real trading skill but demand real economic infrastructure. Key decisions: what moves prices and how discoverably (event-driven markets need the event-price link learnable; random walks are slot machines with tickers), player market power (can a rich player move prices, corner supply, crash rivals — manipulation is the fantasy's dark half and needs rules), and time friction — real-time markets in a pausable single-player game invite save-scum arbitrage the design must decide to accept or block. Pitfall: the market as riskless faucet — when one strategy (buy before the obvious mission, sell after) prints unbounded money with no failure mode, the market isn't a system, it's a cheat code with a spreadsheet skin; markets earn their complexity when losses are genuinely possible and the player's edge must be built, not scripted.
