Just in case nobody knows, the console ports were updated with Back to Saturn X E1 being added, even with some changes like level names.
And BattleMode gets new content like the retro/Quakecon podiums, a classic based Revenant and a cosplay skin for Doomguy.
The more i see of Eternal's additional content and online stuff, i wonder how it can be preserved/accessible/documented/interacted/customized for the future.
For a series about longevity and costumization, i fear that any bit of content is lost in the past or locked from something specific, specially since the new games broke franchise records and are so well recieved, i don't see the point of this event/service stuff and how you get these skins besides just getting people more dedicated to the game.
I've seen complaints about how Twitch Prime isn't in some countries or BethNet screwing up with how you can get skins or even play single player.
And besides that and that one Denuvo anti-cheat thing, i hope id is considering some post mortem plan for the game because much like the older Doom's, you'd soon have to leave it to fans to carry the game, depending on what happens to Battlemode, Empowered Demons, invasion etc and whatever the modding will be like.
Or even some re-release with every bit of content and feature in, along with more control for the players and making sure nothing in it ever dies because of lack of internet or some service/subscription thing, whether it's Twitch Prime, BethesdaNet, Slayer's Club or whatever.
Doom 2016's MP and SnapMap weren't popular but still had unique features and even bits of lore, along with some impact on mods like D4T and MetaDoom.
And there's also stuff like the arcade mode's scores or player deaths in UV.
Doom 3's multiplayer is barely documented or given attention, even about its access and the BFG edition mistreated that game.
VFR? I'm not sure how if that game ever had some non-VR playable mode.
Mobile Doom titles are almost lost, hard to find, require emulation and updates on modern phones broke them from what i recall.
And 64's legacy came from unofficial/fan ports that soon lead to an official one and, you know what? This is becoming a topic on its own but i feel like every bit of Doom (Or any games) should be "eternal", even the less liked ones and in this day and age, even the Internet Archive is on an unfortunate spot and so many companies want to have their own Netflix.
Even stuff like concept art, lore book pages and OST music selection could have been in the games for some digital preservation/access.
I just thank that Carmack even released source codes of his games and feel like what i'm saying is something that even developers would like, since it could benefit everyone and have no downsides at all.
Being a series where gameplay comes first, it makes sense documention of the games involves interacting with them, since it fits the medium too.
Anyway, one reason to explore the classic games aesthetic is to get details like how classic Doomguy's head is "flat" on the top, which also applied to classic BJ Blazkowicz.

Honestly, i think some low-poly-ish/cel-shaded art style could fit Doom, like Quake styled models with Doom's color palette that could bring the Doom art style to 3D by keeping some 2D elements.
