In this game you run into enemy ambushes, hunters fighting machines and enemies getting mollywhooped by machines at random moments, you can choose to join in or get the fukk away from there
It's not as "alive" with NPCs as other open world games, sure, but it's not dead at all. Machines reacting and ganging up on you if you fukk around has always been the "danger" of this franchise and Forbidden West improves a lot from Zero Dawn.
To be honest the biggest flaw this game has is that the plot took a hit compared to the first one.
