DOOM Eternal just didn't do it for me, the same way that 2016 did.
Whilst I liked a lot of the additions, and the game felt like a true evolution of what DOOM can be, I ultimately felt that there was just so much crap that got in the way.
Constant puzzles, constant platforming sections, constant cutscenes. Im here to slay demons, not literally jump through hoops. Not that I felt that the game's story was getting a bit to big for its boots - origins of the DOOM Slayer, ghost kings, betrayers, yadda yadda yadda - who really cares?
I just ultimately felt like DOOM 2016 was a more consistent game.
As for what my game of the year is? I dunno. I've been generally disappointed with new releases for the past few months, and even years, and nothing has really jumped out to me as the game to play. That said, the best game that I have played this year, was definitely Hades by Supergiant.
