I smell a... wumpus!?
Huh? It isn't blurry?

Valley isn't bad for that - not much attacking wildlife, especially early on. Calling it an RPG would be a stretch, though. Kinda pricey for such a short game (~10hrs), so you might want to wait for a sale.
Some planets in No Man's Sky are good for this but not most of them.
All in all, you're probably going to find more of this kind of thing in the puzzle genres.
Balrum has non-hostile wildlife. You can still attack them and if you get real close to a bear, it will go hostile but they'll leave you alone otherwise. Even some monsters only give chase if you invade their turf.
