Before you go rage on me, I think CoD is awful. My point is that all these games are becoming clones of each other.
The best part of Halo was that it was NOT CoD. Yet with every new release it seems we are heading closer and closer in that direction.
Stop trying to do a better CoD and focus on making the best HALO. Accomplish that and you will see Halo return to the throne of the best console FPS franchise (although imo it still is).
