Re CYOA/RPG combo, I believe you're referring to the Fighting Fantasy series: https://en.m.wikipedia.org/wiki/Fighting_Fantasy https://en.m.wikipedia.org/wiki/Fighting_Fantasy There's a fun confusing fact about that series, which is that Steve Jackson was one of the creators and frequent authors. "Oh, Steve Jackson, the creator of GURPS and Munchkin!" you're saying. Nope, different Steve Jackson. But wait! That Steve Jackson did come along later and author a few books in the series. So now a bunch of those books have "Steve Jackson" listed as the author, and there's no way of knowing which one it is without googling.
