Hmm, thats a very deep idea. Right now, game play videos are just for actual players. Make it a watchible for ppl from "outside" that could be a challange.
First, you would probably need some gifted comentator. I had a chance to stumble over some guys who could be pros, when i was playing Company of Heroes (pc game). Even my friends, which didnt even play the game once could watch it and have a fun despite they didnt fully know the game.

But thats just me mumbling for my self
You are doing a great job and i cant wait for another episode
