A shooter is a shooter its not a rocket science formula but what sets one shooter apart from another is the "atmosphere"...the feel of it.
World at War MP seeps atmosphere, its grimy, its messy and its a downright killzone, from your bloodied stump of a leg having wandered into a betty to getting a faceful of Alsatian dog.
When I play WaW multiplayer I think, "yeah, this can't be that far off what the landscape was like"...the program crew have really put the effort in with the little touches that an old school gamer notices. On the German / Russian maps there are times when your view gets obscured by a sudden cloud of smoke, on the Jap maps there are swarms of flies.
The guns are old and "clunky", in computer terms they are analogue giving a nice solid "rat-a-tat-a-tat-a-tat" rather than modern 100,000 rounds per minute of point and spray "kill EVERYTHING"....WaW is all about gory subtlety that not everyone will get.
Of course its horses for courses, one gamers nirvana is anothers dullsville but IMO every single World War II shooter in gamerworld has led up to the ultimate pixelated expression of that conflict in WaW multiplayer, and I should know having started off on a Sinclair ZX Spectrum in 1982.
