FPS are a boring unoriginal genre, most companies arnt doing much in the way of innovation in the FPS department... IMO COD was the first game to be a really good WWII fps even though there was already like 60... i admit the games before it were good but nothing new or great, all the FPS of the world are pretty much identical except with different skins... actually this holds true by the simple fact that half of them all use the same game engine... sure it gives some room for innovation but nothing fabulous

Hal life 2 is a great game but isnt really anything too spectacular... the only FPS that can hold my attention after beating it on the hardest mode are online games
