Far Cry Primal
In Far Cry Primal, you play a prehistoric tribesman trying to reunite his scattered people while defending against a rival, cannibalistic clan in this unique, first-person action game. There's plenty of graphic violence — including a scene where a character is burned alive. In addition to hunting and skinning animals, you raise companion animals such as bears and wolves, which you can command to attack people. Mature scenes include players drinking blood and hallucinating, as well as female nudity.
Alternate first-person action games: Mirror's Edge Catalyst (age 10+), Star Wars Battlefront (age 13+).
