That's a wrap on Doom Eternal, on Ultra-Violence difficulty. I got the achievements for collecting everything, I'm pretty sure, so I have proof I went out of my way to clear the entire game and not just blast through the main stuff. Well, not that that really matters. The game's brilliant; combat loop is a lot of fun once you start getting it down, world design is amazing, the lore is... well, it's stupid, but it's good for a laugh, and the multiple difficulty levels make it easy to find the point where you get into The Fun Zone. Definitely recommend giving it a shot, though some people might bounce off a few of its idiosyncrasies; for those people, I recommend Doom 2016, which is arguably closer to the original games in mechanics and design.
I don't have the Ancient Gods DLC, and I'm not going to go out of my way to buy it right away. Instead I'm going to pick up another game from my backlog, and the most likely target at the moment is Final Fantasy 7 Remake. Playing a game that's a bit a lot different from Doom Eternal should be a nice change of pace, and I still haven't gotten around to completing it; with the interest I have in Rebirth, it'd probably be a good idea to get a lot more familiar with 'Season 1'.
