So, I'm really liking Black Ops.  Much more than I even thought I would.  However, there is one glaring problem that Treyarch made when creating the maps:
 
There are too many windows.
 
Now, this may not SEEM like a big problem, but it is.  Let me explain:  In this iteration of Call of Duty, you can now dive into a prone position.  Meaning, that while you are running, you can hold down the crouch button, and you will dive a few feet, onto your stomach, and be in prone.  It's kind of a fun little thing that they added.  However, this neat little addition can be problematic when introduced into Multiplayer and its numerous windows.  Why?  Because Treyarch had the foresight to make it so you can dive through windows.  John Woo style.  And once you've tasted the sweet ambrosia that is diving out of a two-story window, landing on your stomach, and killing some poor bastard who never knew what hit him, you will never stop trying to recreate that moment.  I had the misfortune of killing someone in such a fashion as the game winning kill earlier.  That sort of thing changes a man.  You go from "steely-eyed killing machine", to "moron running through gunfire and charging towards glass just to hear that sweet, sweet shattering sound" in less than a second. 
 
Treyarch knew damn well what they were doing when they did this. We gamers are a simple folk at heart.  Oh, sure, we claim to love the artsy indie crap.  But, when introduced to giant fireballs, massive weaponry, and even simple shattering glass, we revert to a caveman state.  Hell, we still lose our shit when we see working reflections in mirrors!  So, I hope the game's creators are happy with what they've done.  It's too late to undo most of the damage.  But, maybe they could make a tutorial to teach us how to fight such impulses?  I don't know.  I'm going to go play a bit more and continue to hate myself when I'm unable to resist the urge to dive.
