How the hell can it be a tactical shooter in WW1? It was about suicide charges hiding in trenches. The only way they can make it work is if they blatantly misrepresent the war.
WW1 was fought, you know, in the whole world. There are places where trenches didn't prevail. In the alps, for instance, was a particularly gruesome warfare, which had even man made avalanches as weapons.
Besides, towards the end of the conflict, the germans were emploing a brand new concept which envolved small assalt troops as a way to break the deadlock. This, plus the horror that they've felt with the allies' early tanks led to the concept of Blitzkrieg.
And, heck, even in the western front and all those trenches, some operations consisted in a two or three man groups trying to sneak in the no man's land to gather information. This kind of thing had the tendency to make the whole hell break lose as soon as the other side notice something strange.
There are lots of alternatives. The key is big money, big develpment cicle and talented people. After all that, whats left is people who don't know squat about the war saying nonsense.
