@jgonzalez I’ve seen that series a couple of times actually, it’s great!😊 doesn’t go very deep into it though..
Perhaps you can document the design stage of the next game course you make?
Record a couple of videos of all the things you do before you start the actual building phase of the game, from initial idea till greyboxing/playtesting. Just to get some insight into the process, it would be most helpful.
‘Cause I think it’s not about the specifics that come out of it (like what mechanics and such, because like you already mentioned every game is vastly different), but it’s more about the thought progression and how you go about testing out ideas and such.
