by CEO Mark Gerhard as "essential for the future of RuneScape". One week later, Jagex reported that the amount of in-game coins brought in by gold farmers was down by 81%; real-world trading was down by 61% and the wealth of those trades was down by 63%. Falador Massacre The Falador Massacre was a historic bug that occurred on 6 June 2006. The bug caused several players to retain the ability to attack other players after leaving a designated PvP location. Ordinarily, players are only allowed to attack other players in player-owned houses, minigames, or in the Wilderness.

The Yahoo! 2006 Buzz Log stated that, "while it may not be as easy on the eyes as some other popular [MMORPGs], like World of Warcraft, City of Heroes, or EverQuest, RuneScape is still a
