Lineage II leads to murder

[Hammerskjold]

I've tried Lineage II before. It made me want to kill someone too.

Dem's fightin words! Light gun at dawn sir!

On a slightly more serious note, it could be argued that almost any game or competition between other humans is a form of ritualized combat. Human being's veneer of civilization is not that thick, so it's not surprising a competition can revert from non lethal back to lethal.

Or these guys could be just plain sociopathic a-h0les. That's also known to happen.
