What are the best exploration based games on PS4?

Every character feels like they have a history and realistic personal motivations, even when they're left unexplained.

Mae's friends are all different yet interesting in their own ways, like Gregg who's always happy to see her and helps Mae feel like someone truly cares, and Bea with her biting sarcasm and apathy that seem to cover up her more complex issues. The residents of the town also talk about things in ways that are true-to-life, like how they gossip about their neighbors as you listen in, or just flat-out tell you sometimes to leave them alone. Every character in the game feels like a real person, whether they're central to the story or just one of the NPCs you see sitting on their porch all the time.
