My Friend: I just got a 12 kill streak on modern warfare 3 beat that!
Me: I collided the sun with a slightly bigger star which then distorted the planets in our solar system, the Earth driffted away and got colder and colder until no life on earth is ever possible resulting in the mass death of over 7 billion people on Universe Sandbox!
My Friend:
Who knew universe sandbox could be more violent then a game where you go round shooting people you met on the internet. ( but I do love Battlefield 3!)
