Agreed on all counts.

1) The new locations look awesome but also feel kind of silly and nonsensical.

2) The plot took a huge step backwards IMO. Doom 2016 had a very slick plot presented entirely in-game, and it held together very well. Doom Eternal has some ridiculously complicated monstrosity of a plot presented by codex entries that you slowly pick up and then have to read through.

I never liked the name "Doom Slayer" (they couldn't have done "Doom Soldier"? Really?) so I do like that they are now calling him "Doomguy." But it was much cooler when he was a faceless force of demon-stomping, "unstoppable, incorruptible, unyielding" like in Doom 2016.

3) I'm fine with the humor, but the base is annoying. Sure, it's massive and impressive and whatever, but it takes way too long to walk around between missions.

4) Yeah, I get what they were going for I think (make the single-death difficulty playable). But it still feels weird that loading your checkpoint save-game doesn't restore lost lives. Those are just gone.

But yeah, I'm really enjoying it overall too.
