Is this the “Hunger Games” book and movie series?
Nope, it’s a Video game series that they are in discussion to make into a TV series. Some of the ideas in it do overlap though.
Think of it sorta like the movie, “The Day after” except 200 years later and what transpired. The more realistic aspects explore how survivors handled/ed the aftermath of a nuclear war. The roving tribes of ferals, the scavenging, the rape gangs, the attempts at restructuring a civilization in/from the remaining ruins, the search for old technology to elevate them from that existence and recapturing lost knowledge.
It is a huge and well thought out ‘world’ they created for the story..
