I don't even play video games anymore fuckface. I have better things to do than let pre-teens scream at me over xbox live.
But seriously, are you going to tell me those 2 series aren't played as fuck? COD puts out a new game every year and a half or so and it's nearly the same every single time. what are they on now, 9 or 10?
As for Halo, they ended the story line with Halo 3, then came up with about 3 half-assed knock off games after that, and now they're trying to re-start it again with Halo 4? Yup, and they do it because they know mindless consumers like you will keep paying $60+ each time they release a new game, no matter how played out and retarded they may be.
I wish I were as simple as you, it's probably way easier to find fun.
