I’ve run all kinds of RPG campaigns, but I’d say the majority- regardless of system- would be considered PG-13.
Between PG-13 and R. Action level about the level of an Avenger's/Marvel movie. Can get up to R if I'm feeling like introducing some Alien/Aliens level terror.

I'd say my games are pretty solidly PG-13 with the occasional foray into mildly R territory, which I think the local M (mature) rating covers pretty well. (All of the Disney-era Star Wars films are rated M here in NZ, for instance.)
The NZ system also has an R13, but I don't think I'd use that to classify any of the games I run. I'd easily rate the one I play in as R15 or even R16. The DM can get a bit graphic in some of his depictions, and there's more swearing and adult humor than what I'm comfortable with when I'm DM.
A bigger problem, in my opinion, is that these ratings are... basically insane.The problem with these ratings is that they are one-dimensional, covering violence, sex, horror, other themes (slavery, etc.), etc.
