Okay After some research I found after seeing another post about how Halo 4 is like cod let me clear some things up Correct me if i'm wrong
Sprint was originally in super mario bros, Doom, and wolfenstein 3d
Loadouts were originally in Diablo 1 (don't have much info on it)
Iron sights were originally in Wolfenstein 3d and of course Doom
GUNS were originally in IDK almost in every game before 2003!
Thats what people were usually complaining about, if you have more informations tell me
Now, after reading this, you can't keep comparing it to COD! since it wasn't the first game to have sprint, all you cod fanboys keep thinking that COD owns the rights to sprinting, loadouts ETC....
