I'm currently playing the game, got like a handful of levels left. It's a good game, but with the way the Doom games have evolved and changed over the time, I don't think you can really say "if you like that Doom, you'll like this Doom."

I definitely enjoy the gameplay of Eternal more, but Dark Ages is really good.

The feel of running around is great. You sound massive, your jumps create shockwaves and kill enemies. If you've played Boltgun, it's like that.

The shield is feels great. The charge is awesome, just like the Meathook was in Eternal to get right next to your enemy, and fodder demons just explode on impact.

Parries feel good, but are extremely easy. The timing is super forgiving and the range is massive.

I think a big thing, that not many people are talking about, are the difficulty sliders. You can change so many things, but ID just ignores 90% of them with their presets. You can change so much stuff, and make it feel like a completely different game. Crank up the game speed and just zoom around. Increase your and the enemies damage, so it's all about dodging, or you get one-shot. Make the projectiles slow, but a lot more deadly.

There's still some ammo management, but it's not like Eternal, not even like 2016. Your melee attack, that you can use for the execute drops ammo, just like the Chainsaw, but you're using it regularly anyway. Some guns also have upgrades that shooting demons with it also drops ammo for the weapon.

The game is a lot more story heavy, but just like in Eternal you can just skip it and not read the Codex entries.

The mech stuff is alright, but pretty basic, but also really short segments. The dragon is cool in theory, but I really hate these parts, and they just drag on for far too long. Flying around just isn't fun.

Weapons are pretty good, and I have some favorites. The normal Combat Shotgun with upgrades is great this time and not just outshined by the Super Shotgun immediately. That Ball-on-a-Chain gun is also really nice, with some cool upgrades. Because you don't really have any ammo issues if you use the melee regularly, I've just used one gun for long stretches of time, because there's just no reason real reason to switch, and you can just use what you want.

The devs always said in Dark Ages you're like a tank, but with default settings on Nightmare difficulty, you're made out of paper. Projectiles are extremely dangerous, and enemies like to spawn behind you and shoot you in the back. The game is actually not great on telling you where you're getting attacked from, and there's just always tons of enemies around and some deaths can be kinda frustrating.

Then there are also some minor UI/UX issues. You get small icons in the middle for your melee charges, but they don't show the progress like in Eternal with the Blood Punch. There's no dedicated Map button, just open your Dossier, which remembers your last screen, which is annoying, because you want that map 99% of the time. Sprinting has this terrible vignette effect around your screen, and you want to sprint all the time, but you can only disable all screen effects, which includes some stuff I'd like to see.

For some dumb reason, the Fast Travel option, at the end of a level has been removed, so if you miss a secret, you'll have to play the level again. There's also tons of points-of-no-return, so you'll have to stare at the map constantly, to make sure you haven't missed anything, which makes the lack of a map button so terrible.

After I'm done with my Nightmare run, I want to do another one, where I play around with the sliders a bit. I want to turn up the game speed, but will probably lower the damage and projectile speed to compensate.
