Imawa no Kuni no Alice (2020)

Arisu Ryohei—a listless, jobless and video-game-obsessed young man—suddenly finds himself in a strange, emptied-out version of Tokyo in which he and his friends must compete in dangerous games in order to survive. In this strange world, Arisu meets Usagi, a young woman who’s navigating the games alone. After a dangerous game which tests Arisu’s limits, the two set out together to unravel one mystery after another as they risk their lives and confront what it means to live. (Source: Netflix) ~~ Adapted from the manga series "Imawa no Kuni no Alice" by Haro Aso.

Thieves overtake the mint of a unified Korea. With hostages trapped inside, the police must stop them — as well as the shadowy mastermind behind it all. ~~ Remake of the Spanish TV series "Money Heist" (La Casa de Papel) [2017].

It is another survival game but this one has no set up and is more like "Hunger Games" than an unknown higher power running the show.
