People are tired of modern/futuristic FPS that was pushed by CoD in the last years to the point of saturation. WW1-2 is giving fans a fresh air until it becomes saturated, they get bored again and demand modern shooter. Then the cycle repeats.
WW shooter -> Saturation -> Modern/Futuristic shooter -> Saturation -> repeat.
And? I don't care what other people like/want. I'm just saying I'm not interested in a WW2 shooter (and never will be).
Bet Shiken that COD would outsell Battlefield in 2018. http://gamrconnect.vgchartz.com/post.php?id=8749702
