I didn't expect to love 2016's Doom reboot as much as I did. After a period of wild and wonderful experimentation in the 2000s, the FPS genre seemed to have settled down into a comfortable groove typified by the likes of Call of Duty and Battlefield, with a focus on scripted setpieces and one-off gimmicks.
There is a whole lot more to the FPS genre than Call of Duty and Battlefield and it kind of bugs me that so many people here try to make it seem otherwise. I'm a fan of several FPS series and I don't even play Call of Duty or Battlefield and have no interest in either one. They certainly do not typify the entire genre by any means.
