LOAN/DEBT SYSTEMS
Borrowed money with obligations — loans to repay with interest, mortgages structuring the whole game, debt collectors as consequence.

Animal Crossing's Tom Nook built the gentlest and most famous version (interest-free, deadline-free mortgages that structure progression as voluntary aspiration), EVE Online and player-market games host real lending economies, sports and tycoon sims offer emergency credit at punishing rates, and Recettear's shop-debt deadline gives its whole loop urgency. Designers use debt as a goal engine: a loan converts an open-ended economy into a directed one — the number you owe is a quest that money itself completes — and repayment schedules create pacing pressure that pure accumulation lacks. Debt also lets players time-shift: buy capacity now, pay from its proceeds, which teaches investment thinking and adds a risk lever (leverage amplifies both growth and collapse). As fiction, the debt collector is among gaming's most reliable motivators. Key decisions: hard deadlines with failure states (Recettear's game-overs) versus soft perpetual balance (Nook's infinite patience — motivating without stress), interest rates that matter without spiraling, and what default actually costs, since toothless debt is just a progress bar wearing a necktie. Pitfall: mandatory debt that punishes the wrong players — struggling players forced into compounding interest enter death spirals the wealthy never see, making the system regressive; the best game debt pressures the comfortable and forgives the drowning.
