In Horizon Forbidden West, players continue Aloy's quest to protect the balance of technology and nature that helped revive planet Earth after a rogue swarm of military robots wiped out all life some centuries prior. Yet, as in most open-world games, there's a sort of ludonarrative dissonance at the core of the experience given Aloy is able to ignore her world-saving quest in favor of collecting Black Box recordings or helping various tribes through their day-to-day woes.
Developer Guerrilla Games was smart enough to give nearly every side-activity a purpose at least tangentially related to the main quest. Helping various characters through their hardships may gain Aloy allies for future altercations, and things like completing Horizon Forbidden West's Cauldrons sometimes affect the larger world on top of giving Aloy new machine overrides. Much of it is just good worldbuilding though, and a great example is the Gauntlet Runs that establish an extreme sport reminiscent of the post-apocalyptic desert car races in Mad Max: Fury Road, or the more aptly named Death Race film series.
