I think the idea of having quizes, or aptitiude tests, that develop into an assessment (or conversation about) the participant's own abilities is a great idea. A modification I would suggest is that when something is pitched as a quiz, when the focus suddenly changes to the player's own abilities, maybe the transition isn't very smooth, like "this isn't what I was expecting".
Perhaps pitching it as a 'question' (more generically) would avoid setting expectations that you have to subsequently break.
I can riff off that idea. I agree with what you say and want to develop it more.
In other sports personalities and preferences become clear after a few experiences.
Someone tries football they dont like getting hit, they switch to defense.
Someone tries baseball they can't hit but they can throw.
In pool, most players don't even have the vocabulary to describe what they are doing on the table.
Other sports romanticize foul shots, teeing off, or a great throw.
In pool understanding the intricacies of pool takes educating. And DrDave tries and has a following but, if it stopped growing that means max capacity has been reached. Or try something new because that cow is milked.
Promoting pool as try 14.1 or try 9 ball or try being a defensive player or offensive player.
The idea is connecting their potential or preferences to a playing style or game that suits their current skills.
Its self assessment and guided instruction.
