Well, a game that's 12+ in this system looks like it would have to cut off at foul/aggressive language, violence, sexuality, drug use, corpses, and blood, which sounds about on par with an ESRB rating of T for Teen. Cyberpunk is going way beyond that into glorifying drug use, excessive violence and sexuality, nudity, gore, etc., so it's going to be a hard M about on par with The Witcher or GTA. Perhaps pushing it a little further than that, but not by much because an AO is not an option, obviously.
