Doom Eternal
I loved this game so much. The breakneck speed was what made Doom 2016 so great, and Eternal takes it up another level. Double jump, double dash, and air control are all available early in the game, so for almost the whole time you are way more mobile than ever before. The threat progression in Eternal is also fantastic. You are gradually forced to learn how to play, then to consistently use all your abilities, then to use strategy. And then toward the end it throws everything at you and it becomes blissful carnage. 2016 was basically blissful carnage all the way through, which was very fun, but I definitely like how this time there is more variety to the stages of the game. Favorite levels are Doom Hunter Base (best level design and memorable visuals for me), Mars Core (hilarious slayer gate), and the last two levels (bliss).
Only complaint I have is the Rocket Launcher changes. Remote Detonation Rockets was my favorite gun in 2016, even above Super Shotgun (which is my favorite for Eternal). It was much harder to get direct hits than with lock on, but if you got all direct hits I think it was probably higher DPS. In Eternal the rockets feel slower and more awkward to fire, and there is no reward for aiming skill anyway because lock on will easily do more damage no matter what.
