why now

[@MarphitimusBlackimus]

12:26 This textual inconsistency was, of course, fixed in the Game Boy Advance and iOS ports of Doom, changing the shotgun shell pickup text from "Picked up 4 shotgun shells" to "Picked up the shotgun shells" and "Picked up shotgun shells", respectively (the latter iOS fix being made by Carmack himself, as indicated by his comment in the source code), hence not specifying the exact number of shells in the message. And that's why all true Doomers today regard the GBA and iOS ports as being the definitive way to play Doom.

[@AB0BA_69]

Good to see you around, Marph! Please post more nerdy HL videos! 😊

[@MrCantStopTheRobot]

Ridiculous. DooM was always meant to be played on Nintendo Wii.

[@roblammens]

What a load of crap. Everyone knows the definitive way to play Doom is in the Doomsday Engine with every single "Modern Graphics" mod you can find! The 3D models and dynamic lighting definitely don't look just like shovelware!

[@StillTheVoid]

Now its your turn for another half life lore.

[@the_kovic]

An even better solution was implemented in DOOM 64 which dynamically changes the message between "Picked up 4 shotgun shells" and "Picked up 8 shotgun shells" based on what difficulty you're playing on.

This is what makes Romero a legend in gaming. He's a gamer's game designer. Outside of some level design, Romero was just an idea guy that understood his customers.

[@TheTrueNorth11]

[@silky_merkin]

For sure. Every good company needs that charismatic "face" and personality of the company and Romero always fit that role (a little "edgelord" sometimes, but it is Doom, satanic references, demons, etc.) , even if others on the team were more technically savvy.

Nightmare difficulty always intimidated me as a kid. When cheat codes didn't work, it felt like the difficulty itself was overriding the game rules, like the monsters were just too powerful to be affected by the cheats.

[@RustBot42]

I unironically love that feeling when a game goes "No. You must suffer." The trepidation you feel, that if the difficulty mode takes away the tools that makes you feel safe, what other horrors is it hiding under its cloak?

[@drakep.5857]

​@@RustBot42 games instilling a sense of fear and mistrust within their hostile worlds is one of their biggest strengths as a medium. System shock 2 is a masterclass at this.

[@BigMacDavis]

That was a really cool backstory. I had heard rumors that Nightmare was added in as a joke difficulty in future editions of Doom after 1994, but never actually got them confirmed until right now. I think I'm gonna give NERF a run through. It looks fun.

[@ravagerslb]

Gzdoom currently has an option for monster nightmare reflexes, meaning you can play "two thirds nightmare", fast monsters and reflexes without the respawning bit. Can be interesting for those who want an "in between" challenge between uv-fast and full nightmare.

[@DinnerForkTongue]

You can also activate double ammo pickups for 3/4 of the experience.

[@ravagerslb]

@@DinnerForkTongue without respawning monsters, double ammo pickups feel "cheap" IMO

[@DinnerForkTongue]

[@billiam6398]

haven’t played with the ammo setting, i imagine that could enable one to play 4/3rds nightmare by disabling the bonus ammo.

That is indeed my preferred 'hardest difficulty' option for the base games. The respawning enemies sucks for me as somebody who likes to take my time rather than rush.

"Oh really? Ok then. You're all dead." Great response John Romero

John Romero's version of Kenshiro's "Omae wa mou shinde iru" ("You're already dead.") around the time of that famous manga when it first appeared in the 90s. Great minds think alike, apparently. 😆😆😆

[@garuelx8627]

@SaviourV I feel like it's more of a call back to the OG Leisure Suit Larry games when you enter "cheat" in the text command box. The game says, "Ok then, You win. (game over)" And it exits to DOS

[@SaviourV]

@@garuelx8627 Ouch. Still, I think that the Leisure Suit Larry reference you mentioned is a slap on the wrist compared to John Romero's response here. On a side note, aside from decino's battle against John Romero (multiplayer deathwatch), have you seen Coincident's final "Corruption Cards" battle against a Romero super-boss yet?

[@smgamer240]

[@T-West]

After playing on NIghtmare it's amazing how fairly-balanced it is. Definitely not a joke at all. The need to juggle moving forward before enemies respawns while also clearing out faster-firing demons works incredibly well.

[@redline841]

The difficulty game mode is a joke. It's just a very well crafted one.

[@riffbw]

It definitely was a joke, and given strategies and tactics of the time, it was deemed impossible by many players. But as we know, gamers adapt to any challenge and the advent of circle strafing, better use of a mouse, and optimized strategies have made it very doable. It just happens the joke was very well designed that it works out as an asset to the game rather than being just a joke. Now Wolf3d with respawning enemies would be a joke.

[@DinnerForkTongue]

It is, but not by design. It's the gamers that adapted, overcame and grew to enjoy it.

[@PeterLawrenceYT]

Monsters going from set dressing, to constant and persistent threats is why I love Nightmare, as well as routing which is super fun.

I find it really cool when game devs respond to fan questions and messages like John Romero did here.

[@LPavownage]

One way I tried mixing up Nightmare Difficulty was by adding a new difficulty setting via MAPINFO that also enables Total Infighting, creating a much more chaotic nightmare scenario where even the demons are fighting each other - and I think they remember who they were fighting when they died, too.

[@SaviourV]

Did they stop their infighting long enough to notice Doomguy in the middle of the chaos? 😅

I can appreciate the hustle and skill required for Nightmare, but it's just not for me. My playstyle has always been slow and methodical. I prefer the stuff that die to stay dead. With that said, I still appreciate some difficulty, but I just go for the more difficult WADs for that. Besides, I just can't play the old Doom maps anymore. Pretty, modern maps have utterly spoiled me.

[@BlazingOwnager]

Can I just say how awesome it is Romero cameo'ed in this! I'm glad he appreciates this channel. I've always thought his departure from iD was really the death of the original company. John Carmack was the brains. Adrian Carmack was the looks. John Romero was the heart, American McGee the soul and Sandy Peterson was all the other necessary organs to keep the greater whole alive. That specific mix was lightening in a bottle and since they went their separate ways, I've always felt something was lost.

[@TheWeedlover2]

The Diablo 2 sounds when explaining the instant death pinkies are a fitting touch. It was absolutely awesome of Romero to give a detailed reply like that. The man is one of the coolest people to ever be in game development.

[@XenoSpyro]

I only recognized the Weaken Curse sound. The other one just before it was new to me. A more fitting sound for that explanation would have been Decrepify though, since you know, it slows you down.

Fun fact, in the SNES version of Doom there were no respawns on NM difficulty. I'm guessing due to hardware limitations.

[@hoodedman6579]

It's kind of funny, most other ports didn't have fast monsters but did have respawning instead; I think the SNES version was the only one that had it the other way around.

[@heneedsomemilk655]

...oh, so *THAT'S* why I would always get insta-killed by Pinkies way back when I played Doom95. The pre-game Windows launch configuration panel of Doom95 had checkbox options for enabling 'Fast Monsters', 'No Monsters', and 'Respawn Monsters'. When FM was enabled I could never complete the game because the Pinkies would progressively get faster whenever I came back and loaded a savegame, to the point where they'd just lightning-flash to my location and kill me instantly, through a blur of a red screen. I eventually wised up and made sure the FM option was always de-selected. You solved a 2+ decade old mystery for me. Thanks, decino.

Great video and amazing editing as always! Those cartoon running Pinkies got a good laugh out of me. Your Nightmare playthrough of Doom 1 inspired me to give it a try myself and it really does put a fresh spin on the game. I used to dislike the idea of respawning enemies, but holy heck does this get the adrenaline going. In some ways it makes levels with backtracking more interesting, because you may enter the same fights mutliple times from different positions. Coming up with smart routes and strategies is also super fun. Despite the many failed and painful attempts, I think I'm slowly falling in love with this game mode. I'm currently stuck on E1M7, but I'm determined to finish at least the first episode!

I love the Damn I'm Good (Nightmare equilevant) in Duke Nukem 3D because enemies respawn but they don't respawn if they are gibbed, even corpses can be gibbed.
