History Headscratchers / Doom

** I don't know. Was DaVinci serious when he painted the Mona Lisa? Was Michaelangalo serious when he sculpted David? Was Dickens serious when he wrote "Great Expectations"? We can only be grateful for the final product.

*** Seduction might take time in normal circumstances, but these men haven’t seen a flesh and blood vagina in months, if not years. Like soldiers, sailors and convicts before them, even the straightest man has likely been up someone’s butthole by this point. Seduction would take less than a second.

*** Zombies never teleport in, with the exception of the Commandos. If you played Doom 3 then you'd know that.

* Is it me or did Io go through some terraforming by the time of ''TNT: Evilution'' and ''The Plutonia Expiriment''? As now there is an atmosphere (as Io previously lacked one), no longer is there sulfur raining down from constant eruptions, thanks to the gravitational tug of war between Jupiter and Europa (which is okay, given due to engine limits back then). But the sky lacks the humongous gas giant looming overhead when you're outside (Which could have added to the enviromental feel. Much like how ''[[{{Videogame/Battlezone1998}} Battlezone]]'' did such).

** It's a artifact from the art being done based on the Doom Bible. The game was planned to be set on a massive base on Tai Tanga by Tom Hall but tech limitations stopped that and id moved the bases to the moons of mars but kept the assets the Tech base Computer textures' keep the reference to the old location.

** I did think up a decent in-universe excuse, if nothing else. Classic Doom is set om the moons of Mars, so even on the planet itself you'd expect a thin atmosphere, if any. A gatling design allows you to maintain a given rate of fire with less heat buildup, which might offset the difficulty in keeping it air-cooled. Even assuming whatever's giving the moons earthlike gravity is also maintaining any atmoshere, a normal SMG with that rate of fire might overheat too quickly.

** My theory appleis to both Doom and Doom 3- when demons cross over through the portals from hell to the living plane, they effectively become living beings which makes them vulnerable to weaponry and explains why they have DNA that can be studied. When a living being crosses through a portal into Hell, they become demonic because they entered through means other than death. The same applies to weapons and other items taken through- said items are enhanced by demonic influence and become capable of causing harm to demonic spirits.

* Why did they move the setting of the game from "Tei Tenga" to Phobos and Deimos? Consider the way they are portrayed is [[ArtisticLicenseAstronomy NOTHING like the real Phobos and Deimos,]] it would have been better to just stick with Tei Tenga. Even if they really wanted to have it take place in our own solar system, they could just use Mars itself, as ''VideoGame/Doom3'' and ''VideoGame/Doom2016'' did.

** One of the level designers for Classic Doom, Sandy Petersen, was/is a practising Mormon and used similar logic to justify his involvement - (paraphrasing) "it's OK because they're the bad guys, and it's our job to destroy them"

** The real question is why they'd have to go somewhere new just because you wrecked up the landscape?

** Episode 1 Map 1.

*** In John Romero's homemade Episode 5, ''Videogame/{{Sigil}}, he plugs the gap by saying that [[WordOfGod they happen in the order presented]]. You don't go straight back to Earth after killing the first Spider Mastermind, but go through ''Thy Flesh Consumed'' and beat another one, and then Baphomet/the Icon of Sin messes with your teleport and throws you further into Hell. Then at the end of ''Sigil'' you finally head back to Earth. Since the plot is largely cobbled together anyway, just consider that he finds out Hell has invaded Earth at the end of E3, but doesn't actually get back till the end of E5.
