I'll be straight with you: Doom 2016 knew what it was, and focused on that so hard you couldn't help but respect it. If "louder bigger and better" is them doubling down, then I can't see how they can fuck this up.
I think the better option is to add more animations, specifically, multiple weapon specific Glory Kills. They did get a little tired a million times in, but the mechanic was tight, and it felt good to perform, just needed a bit more variety.
I'm SO excited. BEYOND happy with everything they showed. The whole invasion thing sounds crazy, and I love all of the throwbacks to the original DOOM 1/2. The classic looking enemies, the classic looking weapons, and pick-ups. SO GOOD!
I was REALLY hoping for release date talk or a collectors edition reveal or something. I for SURE thought it was gonna happen, especially since they showed SO much gameplay.
