There are some very good points in some of these replies.
I especially like the direction of Roscoroo's thinking.
We could (the community) make a series of films covering all the various aspects of the game, complete with voiceover instructions and in-game visuals. No small amount of work, mind, but certainly do-able. Even easier if the thing is done in chapters, by diverse people.
The collected library could then be hosted/posted by HTC on the main website (that would be their contribution, since the HTC resoures are stretched so tight).
Might even be more useful to a noob than text would?
I gotta try editing films, and see if this'll work.
