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.
