From what i heard, Romero and Carmack themselves seem alright with MicroSoft owning id and i think Carmack even showed interest in possibly reinteracting with id.
I hope MS treats id Soft and others better than ZeniMax, who probably still had a grudge against Carmack to this day and even forced him to remove some text from the vinyl release of Quake's OST.
If we're somehow lucky, the source code release narrative of id may return or at least be less restricted, since one of Doom's and id's most important legacy is letting people actually keep it "Eternal".
There's just a lot to be said about this situation, whether it's that video with Bill Gates with the trenchcoat, wads and gifs with anti-Bill Gates/MicroSoft messages, Halo, Marathon and even Apple, Death Battle etc.
I feel like Doom and Halo being both under the same company (And whether or not they'd do a crossover together or with something else) is another reason for the new Doom games (Or a future one from a different era, even) to keep exploring/analyzing classic Doom's art style.
Because ever since 2016, Doom ended up having a bit more in common with Halo and probably not just the Praetor suit (Which is ironic, considering some people saying Chief copied Doomguy and Halo "killed" FPS, back in the day).
But in general, it'd help if Doom finds new ways to feel more distinct because its identity is fun to explore and the amount of interpretations and even mods people made out of Doom shows this.
Doom might as well be like Sonic, where there's some unofficial "templates" that inspires content, whether it's Sonic OC's or some Realm667 assets.
Not sure how an actual Doom x Halo crossover would work but i wonder if someone were to put Chief in Samsara or even make a heavy GZDoom TC about this concept.
This reminds me of when Disney bought Fox and people talked about the X-Men in the MCU (In general, monopolies can be a scary thing).
In fact, if this affects Smash, i hope Sakurai considers exploring Doom's identity and even works around making sure Doom and Halo feel a bit more seperate.
In other news, Decino made a final video on being a "pacifist" in Doom 2 and i just think this looks neat
