It completely lost all the tension and atmosphere, as well as exploration. The combat of 2016 was distilled to its purest form with Eternal, and some levels genuinely looked nice, but progression was annoying with all the start and stop thanks to tentacles, puzzles and trial and error with the climbing/platforming. Not even going to get into the nonsense that is the lore. They need to seriously scale things back with the next installment if they're to hold my interest. I was insinuated to get Doom 2016 2 or Doom 2019 and ended up getting w.e Doom is suppose to be now, a borderline parody of the source material?
As for Quake there's something there with the first game, they could take it to all sorts of interesting places, it could be straight up survival horror or a slower, more methodical action game. Hopefully both, since not everything needs to be OTT and cartoonish.
And personally, MachineGames shot themselves in the foot with a minigun ad infinitum with the last Wolf, which was almost seven years ago now. Youngblood/Cyberpilot doesn't even count. That series frankly needs a reset too. Every other company got a shot at the IP, and MG has been hogging it for a decade.
