There is an undercurrent of, to use modern phrasing, gooner content in RPGs. The chainmail bikini being the classic example. Rescuing the virgin from the mad cult is another.

Just look up some classic RPG art and you'll find a bunch of examples.
No. That's called writing a novel.
I do play game books some time. CoyA and Fighting Fantasy being the main two.
