Moneysink

Moneysink is a game mechanism that removes money from the virtual economy, usually to prevent a bloated money supply and inflation of prices of goods and services. This mechanism is effectively the opposite of income.

Without this mechanism, the money supply in a game would continually grow, thus giving players so much money to spend that even commonplace items might be sold for high prices due to the ease of accumulating money.

Examples of moneysinks:
 * Training fees.
 * Transportation fees.
 * Vendor purchases.
 * Repair bills.
 * Quest item turn-ins.
