I like strange characters who largely ignore players, following their own unknowable agendas until you cause problems. Skyrim’s giants who’d rather scare you off but will eventually knock you into the clouds. The Borg in Star Trek: Elite Force who don’t even consider you a threat at first. Despairing Hollows in Dark Souls. That sort of thing. I do hope that Rust [official site] will follow through with ideas raised in the latest devblog, for NPC scientists in hazmat suits investigating this strange island of ruins and naked men chasing each other swinging rocks.
