I had actually tried this weeks ago. I traded in my Blops in feb just to clean up my man cave of crazy amounts of blurays and cases of ps3 games.
So one day at blockbuster i decided what the hell ?!?!?!? ill check it out to see how i do, you know justa s a change of pace.
And WOW......such a difference graphics wise. And the speed of the game was to slow. I mean i did fairly well but i couldnt do it for more than a few days.
Not going to lie, it was awesome seeing the weapons and my Clan title and custom emblem on my weapon. I actually prestiged again for the hell of it.
Its still a great game, but the game speed after MW3 just makes it unbearable at times. And like you said, every other game was ended by time rather than kills. maybe ill try again sometime just for fun.
