Sounds like Far Cry Primal
That one’s by far the most interesting. Dunno about “best” (to me, “interesting” adds enough appeal in this case that it’s probably also my favorite, but “best” depends on the player) but definitely most interesting.
What I found interesting was that it, at times, made me feel a tiny fraction of the kind of awe and fear—and power—that I expect Stone Age people really did feel, for similar reasons.
It’s also one of the few games that’s ever taught me a practical non-computer skill. I string my recurve bow the way the first-time longer crafting animation for a bow shows you doing it :-)
