Now would you stay calm if the British or the USA were not in Battlefield 1? I DOUBT IT! Even if they played a smaller role!
It's a video game. Nobody got bent out of shape when the British or the USA were not in CoH2. They added them in a DLC, just like Battlefield will do for France.
Also people aren't going to learn shit from battlefield. You think kids learned about WW2 from playing battlefield 1942? Give me a break.
