What is the “lead” core actually made of in art

graphite. the center of a pencil is generally graphite

black lead pencil, made from a different form of carbon than graphite that is more like coal

personally, i think the games do because it's actually them controlling it. this might cause them to think it's okay to do it for real. as for animated movies i think they are mostly fine because they're animated. also, animation has come a long way causing animated movies to become more real but 30 years ago this wouldn't be as big of a problem as today.
