Even before Hebdogiciel (or maybe at about the same time?) there was "Jeux et Strategies", and it came also with BASIC listings for adventure games. Mind you, I don't recall ever getting one to work...
There were many publications like that, and often they would contain broken code. I sometimes wondered if it was on purpose, but that was actually a great opportunity to go beyond just typing the code and run the program, having to understand the code, and debug it.
