Doom 2016 is fast and frantic, certainly a twitch shooter (just not as fast as some have been).
It's fun, after a couple hours of gameplay it's very repetitive with not much variance in the enemies (at least so far).
I know this type of game is expected to be repetitive so that's not a knock against it, that's just how it is.
This was my genre of choice back in the day with Quake 3 Arena and Unreal Tournament but I just do not have the same reflexes so I feel a bit less equipped to push the difficulty to the max (playing on default, Hurt Me Plenty).
The game has SLI issues but ID has said it is coming soon. I set mine to Alternate 1 and it is mostly stable at 4k/60 with SLI 980ti OC.
They need to fix the SLI, a few small bugs and... add an HD texture pack since some of the textures are fugly close up (I know I am not meant to pay attention to that while shooting and running for my life).
All-in-all it's a fun, shut your brain off at the door, game that brings back some very nostalgic vibes (and I dig that).
