Some of the other games in the series were pretty good.
Far Cry 2: Set in Africa. Player is a mercenary, bad guys were arms dealers, a Christian priest plays a positive role.
Far Cry 3: Set on an island. Player is spoiled rich kid, bad guys were pirates, island mysticism plays a positive role through most of the game but ends up being cast in a pretty negative light.
Far Cry 4: Set in a Himalayan country. Player is the son of an expatriate native who is returning home, bad guys are the tyrannical government, Buddhism (I think?) plays a significant role in the lives of the innocents and "good guys" but if the religious leader is given control he slaughters his opponents.
I'd give Far Cry 5 a play.
