I am an avid Call of Duty player. From having played 2 and 3, 4 is a GREAT change to step into the modern warfare area with modern weaponry and modern factions.
Personally I love it, there are a plethora of WW2 shooters out there, so a modern day shooter that is not all tactical (Rainbow Six) is a GREAT change.
The mechanics of it is great, maps are vivid and interactive, the variety of weaponry is fantastic.
I mean come on - how cool is it to be in control of a gunship with the heat sensor on and be blowing up terrorists with big assed guns from the sky?
That all being said, I am a huge suckr for WW2 shooters, and cannot wait for WaW.
November will be an expensive month, Gears of War 2 comes out as well.
