Think of Geralt as a ranger like Lord of the Ring’s Aragon, but with animal instincts and as something of a monster hunting mercenary. Like Mass Effect's Commander Shepard he can be cold and ruthless or kind and altruistic as you see fit. But with the source material, he remains a complex and interesting protagonist regardless of how you choose to play the game. Rather than coming off as a bland cypher, Geralt can react with indifference, compassion or just a dry joke. Just don’t get him too drunk.
