A Share market-like Trade System for RuneScape
If you play the online game you may know Runescape Gold, it is said that from October 2007 to December 2007, Jagex began releasing a series of updates to restrict unbalanced trades. The updates limited the value of items staked in duels, removed player-versus-player combat from the Wilderness, made valuable player drops invisible to other players, introduced gravestones for the items of dead players, instituted systems for assisting players with skills and sharing loot among groups of players, and established the Grand Exchange, a share market-like trade system for RuneScape goods. Collectively, these changes were designed to make it extremely difficult for real-world traders to distribute gold and items to players.
