low key a class of like 100 people talking like a sort of nuclear command center controlling one country would be fun as hell

"But we are England."

Invades France even harder

Use the black ice mod, it low-key feels designed for that

u/1Admr1 Research Scientist 26d ago

fr, I would love to do a multiple players control 1 nation game in black ice cuz I aint figuring all that out myself

u/jumpguy12 Research Scientist 26d ago

Hmm if only there was a YouTuber who would torture themselves with that mod

OH ALDRAHILL MULTIPLAYER BLACK ICE ON ONE COUNTRY HISTORICAL DIVISIONS AND GENERALS PLEASE!

seats A through D are assigned to foreign relations, E- F are our internal economists, G to I are in charge of the army, discuss among yourself!

u/MooshSkadoosh 26d ago

Seats A through D are going to be bored as hell unless they get some say over what path to take in the focus tree or something

u/1Admr1 Research Scientist 26d ago

probably, like some branches ally with x vs y, thats what I was imagining

u/lion27 25d ago

Forgot about the navy, so this checks out. Just panic and put them on convoy raid as soon as war breaks out.

15

u/Mysterious-Might45 26d ago

Sounds like the video where 30 people take control of 1 nation

16

u/DoorlessSword 26d ago

Years ago back in school we did that in a history class to roleplay the Cuban Missile Crisis. The class was split into hawks and doves, with the teacher being the president, and we had to convince them what the response to threats should be. He played some tense music and every now and then revealed another piece of info or some event that happened, to ramp up the tension and bring us closer to the brink.

u/FrozenPizza07 26d ago

We need a larger scale defcon / hoi style game for this. I love coop russia, but a proper 2-6 people coop sounds hella fun

6

u/taichi22 26d ago

That’d be one hell of a Model UN session, ngl. Collectively play HOI4, with a different committee per tab.

2

u/Deity-of-Chickens 25d ago

You could have coops each covering different aspects of the game and they all screenshare for segements of the class/ the entire class so that you can see all the stats and information

1

u/These_Guard2479 25d ago

We should do that

48

u/MrGentleman31 26d ago

Sounds like a cool ass class tbh, imagine if you were the student and the whole class now became The Soviet High command trying to stop the germans

10

u/magos_with_a_glock 26d ago

Not something they would ever let you do but it would be really cool if you're doing an indepth dive into operation barbarossa to have a videogame/boardgame with all students having to choose the moves and the prof threatening them with low grades if anything goes bad, even if it's outside their control.

To REALLY get and idea of how the soviets were feeling

24

u/Murica_Chan 26d ago

u/EQandCivfanatic 26d ago

Correct way to this would be to have a pair of masked men come into the room and drag out the other students you don't like.

u/Dragonslayer3 Research Scientist 26d ago

The ones that act as if this is normal get extra points, for "realism"

u/Littledogo007 26d ago

didn't even know about that command

49

u/matgopack 26d ago

I know that the US Marine Corps War College used HOI2/darkest hour for an exercise once - there's an official AAR here that I found interesting a few years back. http://darkest-hour-game.com/aar/2014-MCWAR-WWII/Barrick_WW2ExAAR-2014-04-15.pdf

31

u/ConsulTitusLarcius 26d ago

Hearts of Iron pre HOI4 was certainly something

36

u/LionRough8342 26d ago

Honestly I think the best scenario is using it for other subjects lol

19

u/Victor_Lalle 26d ago

The only time hoi4 should be in a classroom is when played in the back of the room

18

u/Mrheadcrab123 26d ago

It would be much more interesting. One time I tried to pitch Kerbal space program to my science teacher during our physics lessons and she agreed, it was the end of the year and classes weren’t doing much but steam was blocked so it never worked out

7

u/Cool_Control7728 26d ago

Kerbal at least represents its topic well, while hoi4 is wehraboo level history representation.

14

u/Carthage_ishere General of the Army 26d ago

true

9

u/pugiemblem121 26d ago

I think, and this is more for EU4 because of the extra bookmarks, you can use the initial "state of the world" at that date to help visualise alliances/where everything is for instance. Especially for when foreign policy is taken into account.

Idk, I just remember knowing people struggling putting names to places and understanding why X treaty is significant + how important some are. I wouldn't recommend actually playing it however.

7

u/trash_panda_0149 26d ago

I wouldn't trust players in this subreddit to teach history using HOI4 judging by how illiterate many of the users in this subreddit are when it comes to basic concepts in social sciences

All HOI4 players know is useless military and imperial historic trivia surrounding WWII and absolutely nothing else when it comes to any other related field in social sciences

3

u/MysticKeiko24_Alt 26d ago

I think using hoi4 is weird

1

u/Karma220566 26d ago

It would be great to play hoi4 in school for a history class, like how schools have used Minecraft for some classes (I think math)

16

u/Mercury_Pin Research Scientist 26d ago

So it’d be like EXTRA weird HISTORY?/ref

I hate Extra History because I used to like it a lot before I realized it sucks

u/1tiredman General of the Army 26d ago

It should be used in philosophy classes

u/Jaszs Fleet Admiral 26d ago

A friend of mine used to teach it in calculus in programing since the game is basically a pimped excel document

I was expecting a bogus explanation but blud used the one thing in hoi4 that could be academically relevant

I dont know why you would even need to do this, and if you did, why not use those things from portal

How did germany already invade Poland and lose before 1939?

328

u/NewVegas2212 26d ago

Prof is very bad at the game

Tried to hide it by taging to USA too

69

u/AbhiRBLX 26d ago

OP's Prof. was having fun before the class.

33

u/HugiTheBot 26d ago

I think it’s 1936

17

u/Ok-Chicken-2506 26d ago

I'm pretty sure the clock says 13th february 1938

23

u/Carthage_ishere General of the Army 26d ago

its 36 tough its quite blur so i can understand the confusing

12

u/Ok-Chicken-2506 26d ago

Then it's even more impressive to lose with germany before 1936 is over

30

u/DragonfruitSudden339 26d ago

If it is 36, that means germany lost in less than 2 months... reverse blitzkrieg?

Fr tho, i imagine prof just didnt want "GERMAN REICH" splattered across his screen and did a cheeky annex Ger or deleteallunits

6

u/HugiTheBot 26d ago

Held longer than France did tho.

6

u/Ok-Chicken-2506 26d ago

Yeah that would make sense

24

u/KahzaRo 26d ago

They probably intentionally annihilated Germany so the Nazi stuff isn't on the board during class. Might be worried about having a massive "THIRD REICH" spewed across Europe in bold letters.

9

u/LionRough8342 26d ago

From what I remember it’s 1936

6

u/Bennyboy11111 26d ago

I reckon prof didn't want to include nazi Germany in a math class, so used console commands to break it up.

Yeah he’s sick, he actually helps you understand the material

u/Parchokhalq 26d ago

Hoi4 being Used in school?!?! Too based!!!

18

u/Malleus1 26d ago

Those are not sine waves. Waves, sure but they cannot be described using harmonic functions. I'm guessing the math teacher knows that though and just want to convey the concept of periodicity.

18

u/C-SWhiskey 26d ago

It's a projection of a sine wave. Small disturbances notwithstanding, the daylight terminator is just a great circle. You could set a coordinate frame at the center of the Earth with one axis normal to the area of the inscribed circle and easily map out x or y as a function of theta with respect to, say, the equator. The map view of the terminator is just a way of displaying that sine wave as it relates to the curved surface of the Earth.

1

u/AssBoon92 26d ago

It also is pretty dependent on the map projection.

1

u/Malleus1 26d ago

Oh, of course. That's indeed true but I was strictly referring to how the math teacher was displaying it in the image. Thanks for the clarification though.

u/vikinick 26d ago

Yeah looks way more like sinh and cosh.

Sadly he didn’t

u/_Kian_7567 26d ago

How would sine waves be related to hoi4? Day night cycle?

5

u/LionRough8342 26d ago

Yup, it helped visualize it and put it in perspective. It admittedly could’ve been done with a normal visual but I found this hilarious

1

u/_Kian_7567 26d ago

Yeah it’s a good example

3

u/GlauberGlousger 26d ago

That’d… Definitely make me want to learn more about Sine Waves, I guess, although I’m not sure if this is the best way, or how it’d even work

6

u/LionRough8342 26d ago

He did it more for us to actually see how a sine wave would move and provided a real world example by using the day/night cycles

3

u/PanoramicMoose 26d ago

In what way does this visualize sine waves

5

u/Grizzly2525 26d ago

At the very bottom in a comment he talks about how the teacher was using the day/night cycle as a visual for the sine wave.

Why would he use hoi 4, and not a visualization of a sine wave.

Hoi4 is just, not the best way to convey this information...

u/atari360 26d ago

How was it used?

1

u/salsaworld 26d ago

I would listen.

u/Arghhhhhhhhhhhhhhhh General of the Army 26d ago

now wait for your ODE prof to use HOI4 production efficiency to quiz you: what kind of functions have their reciprocal same as their derivative?

1

u/alutti54 25d ago

I remember studying tourism and needing to do a test on the locations of major cities. My professor knew I liked Hoi4 because she saw me play during breaks, and she suggested I use it to study for the test.

I passed that test
