Duels is an online role-playing game and social network that allows users to create characters, buy weapons and outfits, and duel with other members. The site allows members to play against each other asynchronously; users set up duels but do not control the actual outcome. Therefore, opponents can accept duels when you are offline, and the duel will still occur.
Its parent company, Challenge Games, is planning some upgrades, such as a tournament feature, a ranking system, and possible forays into sports gaming. In October 2007, they launched a Facebook application to allow users to battle each other within the Facebook social graph.
In June 2008 Duels held a tournament with $5,000 in cash and other prizes. Over 1,600 players participated.
