Russian news outlet Russia Today is reporting that a clash between two Russian clans bled into the real world, and led to the brutal beating and murder of a young man from Ufa, Bashkortostan, Russia. The two clans, Coo-clocks and Platanium, were reportedly engaged in a bitter in-game struggle that developed to the point where the two groups agreed to go toe-to-toe. The victim's sister was quoted as saying, "I think they have confused the game and reality. And after we buried him on December 31, they continued to threaten us"
It's not clear from Russia Today's account exactly what game the two groups were playing, though they did include a Lineage 2 screenshot. Regardless, it seems clear from the details we have that any link between the violent acts and the games that the two groups were playing is circumstantial at best. That the two groups agreed ahead of time to engage in a fight away from the game speaks to their character. Game or no, these young men were bound to get themselves into trouble. It's unfortunate that their conflict led to the death of a young man, but blame in this case doesn't have anywhere to go but to the participants.
