Riot Games has announced that the Honor sytem has been activated for its MOBA League of Legends. Honor is a non-currency that allows players to reward teammates and opponents for positive behavior.
The Honor system is the opposite of reporting negative actions, and is implemented when finishing matches. Players can rate their own teammates or opponents for being friendly, for their teamwork, or just being plain helpful.
Developer Riot Games stated that Honor can't be traded or spammed, and that it is looking into possible "bonuses for the most Honorable summoners."
