Yes, so Halo 4 is equally as competitive as Halo 2, or rock-paper-scissors for that matter. We all know that anything can be "competitive," but I'm posting under the assumption that we can all make some rational internal conclusions on our own here.
We can argue semantics to make a point, but when the point is asinine, why bother?
Along that line of logic, back to my original post, why would a competitive gamer be excited to play Halo 3 when they can just play Halo 4? They're both competitive, right?
