> playing games where your only goal is to kill (oops, eliminate) people from the other team for hundreds of hours must have some kind of effect on you.
People really tie "kills" in games to murder in real life way too casually. When I play a game it's about strategy, team work, and winning.
A lot like Football (Soccer). It has little to do with the terms or animations used in the game -- those are just for entertainment.
I don't play a game because of how violent it is, I play it if my friends have it and/or it has good/fun game mechanics.
