Since people play games that involve lots of blood, violence, and a "points-per-kill" style...?

Naw i don't think so, i mean i can see where your coming from, but in my case i play a wide variety of games, formula 1, fifa, cod, fable need 4 speed fight night. I personally when picking a game to buy generally look at how much amusement its going to give me (hours of game play in fifas, formula 1 online cod) i don't have any form of urges to kill anyone, drive 200 mph round a crazy corse or repeatedly save the world with a sword and a gun.
