I have been tired of CoD from the very beginning spawning so-called "gamers" that live for the kills and don't bother with any other games. An XBOX to them is a 200 dollar CoD machine. Not to mention the whole FPS genre to me has had few revolutionary games for it, it's all cut and dry to me and it's getting pretty old. At least the RPG has morphed into several sub-genres as well as platforming revolutionizing as well (Mario Galaxy and Super Mario Bros 3D come to mind, and even Kirby's Epic Yarn!). Point. shoot. kill. Where's the fun in that anymore?
If you like shooting stuff, enlist in the military, it'll be as REAL as it gets, plus so hardcore because you only get killed once!
