Happiness is a warm gun

I've been waiting for this day since I picked up COD WaW. Today I hit level 37 and unlocked the STG-44...the gun I would marry if it were legal to marry guns. I'll have to write off my time with the M1-garand grenade attatchment as a sexy fling since any time I use a ranged weapon from now on my monogomy for the STG-44 shall be relentless. I still can't shake my dissapointment with Left 4 Dead. I was seriously looking forward to killing zombies en masse and something about the game just seemed unentertaining. I find almost any shooter that won't allow you to aim down the sight of your gun unbearable, not to mention no upgrades to weapons. I guess I've been spoiled by the rpg game mechanics of COD and RSV2 and anything less has a hard time holding my attention. I'll probably give it another go when its cheaper :/
