"What really started the war was that the non major country that was not apart of SOAP, supported by Huannai which is located in far East of Asia, called Dattorul, a descent of Romania, was the nation where all the requests from jornalists accumulated. The whole place was filled with anti-war posters begging the government to stop the war and the state got annoyed. They were mad that the SOAP wasn't paying attention and now they had to deal with their bullshit.
In Dattorul, drugs were legalized. From the homeless men to president, everyone was addicted to drugs and it was worsened by the Spanish and Mexican cartels. The drug addict leaders made a really regrettable unhinged decision and launched their offensive on one of the superpowers, Fumotaso republic, located in Europe. Fumotaso yelled back at Huannai to keep their pet in cage. Huannai took that as an insult and a threat. So they prepared to fight.
Between the two countries, there was another superpower who hadn't allied with anyone yet. Floraplumeir was its name. It had significant military power that could help greatly in alliance. The two countries persuade Floraplumeir to join their side each. But Floraplumeir was already planning on allying with Abinamasa, located near sunken continent of Africa, who was scheming to destroy Fumotaso and Huannai along with Almondseed, located in Australia.
The reason was they think there should be only a few major countries as they believe their god would reward them more in judgement day as the true strongest country after the world end. So they also secretly intended on invading Floraplumeir.
As for Almondseed, they already got intel on Abinamasa's plan. The thing about Almondseed was that they focused a lot in espionage operations that they had literal schools for training spies without the SOAP knowing. They know this by sending thousands and even millions of spies in Abinamasa. Back to Floraplumeir, the country chosed to side with both Fumotaso and Huannai without them knowing. So that they could also come out on top when the war was over.
After finding informations on Abinamasa, the spies migrated to Floraplumeir and launched multiple hacked missile assaults on Abinamasa, Fumotaso and Huannai. The surprised attack caught all three of the countries off guard. Abinamasa thought they had figured out their plans so they prepared for battle against Floraplumeir first. While preparing, Fumotaso figured out the betrayal of Floraplumeir even though Almondseed did it. While Abinamasa was on their way to full on invasion, Huannai launched a missile attack on Fumotaso.
Confused Flora tried to get aid from Abinamasa and went more confused by their invasion. They then found out the leaked files of the plan on world domination the spies left in Floraplumeir. The four country along with their allies across the globe, fought one another in a bloody war while Almondseed stood and watched from side.
But unfortunately for Almondseed, the civil war from China and India spreaded along with several malfunctioned missiles from Mexico and Spain, had hit the country hard. The war lasted for more than 150 years. That's how the first world ended. Now all these countries are nonexistent."
"How did the whole planet not destroyed with all these advanced technology."
"It did get destroyed but then rebuilt by intergalactic civilizations. The bridge city we live in was also rebuilt. The physical structure of Panxacino may be broken, but the idea of it didn't."
"Oh so that's how... Anyway, you still don't answer what are these boxes."
"They are called 'World War Editions' discs. They had different versions. In order to prevent wars, these disc are used for supressing the warmongering attitudes. We no longer had war since then."
"How do they work?"
"Video games."
"Ahh..."
