Just finished watching the whole game on utube.
Looking at the complexity and size of the maps as a whole, it is more clear now why the level of polish isn't as consistent throughout the game.
They're simply too large to have been completed in the span of their release. I think their claim this time around is 2x as large as doom(2016) maps, If they'd kept it to maybe 1.5x next time around, perhaps there'd be better work balance.
The game is mid-loaded, there's more map polish in the middle levels vs the very beginning/ ending.
The baddies are pretty kewl and well done.
Platforming is, yea, i can see why this wouldn't be for everyone, there's reviewers on both sides of this.
Overall, Tp4 would rate Doom eternal, a Solid 8/10,
for reference
Doom (2016) is an 8.5/10
Rage 2 (2019) , 3/10
