I may have exaggerated a bit, but the concept I was trying to explain still stands.
I welcome more platforming, but it's more than that. In Doom Eternal, the enemies rush you constantly, which means you need to move all the time, combine that with the increased mid-fight resource farming from 2016 to stay alive and you almost get a rhythm of sorts that you need to follow. You have to hit certain beats to survive. The game is designed to force the player to move and always worry about ammo. It pushes you around. I think it's creative and impressive that they pulled it off, but it's very different. Perhaps too different.
Imagine if the Dead Space remake that just came out featured enemies that were twice as fast, so in any combat situation, you always have to move and circle, there was no room for tension, no room for enemies that sometimes move slowly, or anything else than just run in a circle and shoot. It would feel like a completely different game.
And yes, I understand that comparisons like this are mostly stupid, but it's the idea of it, people find that Eternal plays in a different sort of way that they don't like as much.
