Over the span of 24 hours during the Valentine's Day event held in Rift, they have managed to set the Guinness World Record for most in-game marriages in a 24-hour period. Rift has accomplished an insane 21,879 marriages in just under 24 hours to earn them the title. This record has been recorded into the Guiness World Records, and will have a chance to be included in the Guiness World Records Gamer's Edition. All married couples who participated in this event will receive a unique in-game title "The Avowed".
Many games have had marriage systems implemented long before Rift. What's surprising is that Rift is the first one to set this record. This event has probably worked out extremely well for Rift after going semi Free-To-Play as a form of publicity. I look forward to Rift being fully Free-To-Play one day.
