For new people!!! Let them be cool badasses, challenge them every 2 sessions or so, but let them normally explore and experience a new world. Establish the world around them and their actions, but make them the center of attention not you.
You are the set director (setting, tone, rules, and environment) they are the actors and directors. Try to disappear into the backdrop a bit. Then hit them with a challenge.
Or, allow the smorgasbord that is RPGs to come to play. Different worlds, different tones, different challenges every session. Western, sci-fi, murder mystery, fantasy, horror, silly campy (kobolds stoke my baby) type games.
Get them confortable as players, everything changes, but it’s a sheet, some dice, and a fun use of imagination.
