In the midst of PUBG etc, I want to mention that the original Japanese novel Battle Royale is an excellent work of tragic social commentary. The participants are a class of nonconsenting highschool students, and the scenario is presented as cruel and unfair from the word go. The Hunger Games drew a lot of inspiration from Battle Royale. It's worth you time :)
(Not to say that you should feel bad if you enjoy PUBG straight! The mechanic makes for both a good story and compelling gameplay.)
