Yeah, Doom 2016 is easily one of my favorite singleplayer fps games. Doom Eternal is just worse in every way, and I couldn't get through more than a few hours.
It completely breaks the combat flow state that made the original great
Instead of having the freedom to prioritize enemies and weapons, it wants you to do things a very specific way
Instead of the minimal but interesting story from the 2016, we get a convoluted mess, with random characters that we have no reason to care about.
Also, despite 2016 looking quite good, they decided to make Eternal garish and cartoony for some reason??
I could go on, but anyway I hope we get a proper 2016 sequel some day.
