If you're saying this "girl" didn't sit in a corner the entire game, never plays games, and went 22-3 then that is an absolute lie. There's no way she would even have the hand eye coordination to move and aim at the same time in only one match.
I second this. Best I have seen a first time player get, was 10-13. But that's because he always hung out with gamer and learned basics just from hearing them talk.
TC was trying to say that Halo takes more skill, which it does. Any one who plays both at a competitve level and doesn't agree is an idiot. Don't get me wrong, COD does take skill/teamwork. Just not as much as Halo...
