First Person Shooters started arcade slowly became realistic
Call of duty has always been somewhere in between in my opinion
so honestly expecting something more realistic, is your own fault..
over hype is what bums gamers..
Not the Development teams that make the games, and not the company that backs them with funding.
The players bum themselves.. simply put.. This is Xbox 360 guys.. with a franchise like call of duty they don't want to over do it
they know the xbox has limits, look at gameplay from skyrim, RAGE and other new games that were a little ahead.. <and vice versa with ps3..
ps3 sometimes has the slightly crisper versions, or so I've heard but that's beside my thoughts.

If you want to be a critic throw this into your scoring.. fun factor..
that's all that should matter.. people on the sidelines like this, don't matter with the big numbers.
I'm just thinking "out loud" here..
How many thousands of Players that dislike MW3 like BF3 and left some kinda of remark somewhere online?
AND In result.. MW3 Still sold well, did it not?

Personally I haven't even played either yet.. I'm just observing.
