Resources, Trading, and Progression Systems

These terms differ by who determines value.

In exchanging, a player returns resources to the game system at a rule-governed rate. In trading, players voluntarily negotiate with one another. A market changes prices, quantities, or availability in response to purchases, sales, replenishment, or player offers.

These mechanisms move value between the present and future.

A delayed purchase commits resources now for an asset that arrives or activates later. A loan brings future purchasing power into the present in exchange for repayment or another obligation. An investment commits resources to something whose later performance determines the return, sometimes through actions the investor does not control.

Income supplies resources at recurring times according to ownership, position, or a fixed allowance. Automatic resource growth increases resources already present without a new production action. Random production lets a random result decide what is generated and who receives it.

These mechanisms shape how options remain useful over time.

An always available purchase supplies a dependable baseline. A discount lowers cost after a condition is met. An upgrade develops an asset already held. Increasing the value of an unchosen resource adds rewards to neglected options until someone finds them worthwhile.

In I cut, you choose, one person divides a set into portions and another chooses first. Because the divider receives what remains, the structure encourages divisions the chooser will consider acceptably balanced—even when the two people value things differently.

Ownership grants defined rights or benefits over an asset, place, organization, or action. A contract specifies goods, actions, destinations, or conditions that can be fulfilled for a reward.

Ownership creates a lasting interest; a contract creates a focused objective. Both need clear rules about transfer, completion, failure, co-ownership, and what remains available to others.

Bribery offers value to influence another person's action. Negotiation includes broader agreements about exchange, restraint, cooperation, votes, threats, or future conduct. An alliance is an ongoing cooperative relationship among players who retain separate interests.

In an open auction, bids are public and players may respond while bidding remains active. An English auction structures this as rising bids until nobody raises. A turn-order-until-pass auction gives responses in sequence and removes those who pass. A once-around auction gives each person exactly one opportunity.

A sealed-bid auction reveals everyone's one private offer together. In sealed bidding with cancellation, matching offers cancel and the highest unique bid wins. Constrained bidding limits offers to particular cards, tokens, or denominations. A second-bid auction gives the item to the highest bidder but charges the second-highest amount.

In a Dutch auction, a high price falls until someone accepts it. A reverse auction concerns a burden: players compete to avoid it, underbid the cost of doing it, or wait for growing compensation. A Dutch priority auction combines falling effective prices with an order in which players may claim among several lots.

Auctions can sell more than one item in more than one way.

A selection-order bid purchases priority to choose among several lots. A multiple-lot auction lets players distribute commitments among several goods. In a closed-economy auction, payment goes to other players rather than leaving play. A dexterity auction makes physical timing or placement part of bidding. A fixed-placement auction uses defined board spaces to show lots, values, and conflicts.
