The episodes are quick, simple, and provide a basic overview of fundamental systems in a range of games. At the time of writing, he's got five of these episodes available and I can't wait to see where he goes next.
It's similar to what I tried a few years ago here on the blog with my "Game Mechani(sm) of the Week" series, so it is i teresting to see someone else's take on the subject matter.
I suspect future episodes will focus on "Fate" and the "Powered by the Apocalypse" engine, but in that latter case it will be interesting to see whether he assumes the core mechanic as the dialogue of alternating MC-move/player-move in a narrative framework (kind of like the way he describes investigation in the Gumshoe games as a non-dice oriented phenomenon, as compared to the rolling of dice associated with other skills...which is considered a non-core idea)...or if he'll focus on the "roll 2d6, add modifiers, compare to chart of 6-or-below/7-9/10-or-above" which ends up heading in all sorts of directions depending on the specific move taken.
Anyway, go over and have a look. Subscribe. I want to see him do more of these... He might even get around to doing one of my games once the big games have been dealt with.
