One possible element is the struggle for survival. In real life, people face situations where they have to fight for their lives, like in disasters or dangerous situations. This is mirrored in the show where the characters are constantly in life - or - death games. Another could be the sense of disorientation. Just as in real life when we face sudden and unexpected changes, the characters in the borderland are thrown into a world they don't understand.
Yes, there might be some real - life inspirations. The concept of a harsh and strange alternate world where one has to fight for survival could be loosely inspired by real - life challenges people face, like the feeling of being lost in a difficult situation and having to use one's wits to get through. It also might draw from psychological concepts of how people react under extreme stress.
Alice in Borderland is not based on a true story. It's a work of fiction that combines elements of adventure, mystery, and survival to create an engaging narrative.
Overall, Alice in Borderland is reasonably faithful to the manga. Some minor details might differ for the sake of the adaptation, but the core story remains intact. There are no major deviations that would change the essence of the original manga.
