General question.
Do you want to teach the players roleplaying, or teach them to use tabletop systems and juggling rules?
I.e. what is the desired goal, aside from making them gamers? What do you want to expose them to the most?
I see such games not so much as teaching than as a marketing session. So I want to expose them to an enjoyable experience right from the start. Only if this marketing session leads to some success, meaning we have more sessions with the same group and extending the "campaign", I start thinking about teaching them with any clear goal.
Come to think of it, my victims tend to fall into two different groups.
I have frequent contact with groups of students at work. These people are in the mid-twenties, know computers as a normal part of their everyday life, and have at least tried computer gaming in different forms. None of these are real computer gamers, which see computer gaming as a hobby. The idea of sitting around the table to play seems alien to them, but they are used to the fantasy tropes and the concept of a "character".
The other group are people of my age, i.e. in their forties. At some point in their past lives, they may have heard of RPGs but never played them. They are triggered due to their contact to our family and start to ask questions about our hobby. The explanations tend to baffle them, so I invite them to a test run.
Members of the first group are used to select one option out of a limited number of selections. The idea of a limited version of 4e might work for them, especially if one could drop the character sheets and work with a handful of cards only. Sadly, this would remove my reason to buy a new game.
For the second group I want to remove as much of the mechanical burden as possible from the equation or shift it to me. If I tell them "now roll for (whatever)", they should know what to do and not have to ask "what die do I have to roll" and "do I need a high or a low result."
When playing with members of the first group I want to teach them the core mechanics and let them handle the application, while with the second group, I just want to trigger their roll and take care of the rest myself.
