Before COD4, the entire fps genre was cluttered with World War II games. Nobody wanted to experiment. Then Infinity Ward came and revolutionized the genre by giving a multiplayer experience far beyond all their competitors. It also had a relatively fresh modern setting.
Well now everyone's tired of modern shooters too. Titanfall has recently brought players into the future with mechs and parkour, are other developers going to use that as insipiration and create futuristic sci-fi shooters?
Sigs are dumb. And so are you!
