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 :)
The film Battle Royale is sort of in-between. There's a dilution of the emotional core of the book that's really unfortunate due to it getting more caught up in dramatic visual horror elements.
