I think this is a fantastic idea. The one question I want to ask is are you going over mechanics, strategies, or both?
Mechanics relate more to how the game functions. Some examples of mechanics would be: an explanation for how the game moves in 'ticks', how maps are generated, how the game picks what specialist are available for hire, and specialist combat order (especially for global effects in battles with engineers, generals, and kings for which one activates 'first'). My only thought about this is that most of this information already exists between the forums and wiki, but it would be nice to have it all in one clear and concise area.
Strategies would go more into advance tips and tricks for playing the game. This would include specialist combos, and other stuff that I can't really think of right now. But yeah, tips and tricks should basically sum it up. Sorry this isn't as long as the mechanics section but hopefully someone who understands this better than I do can fill in more suggestions.
The reason I bring this up is because I believe it is important to have a healthy balance of both. There are players who want to dig deep into the mechanics of Subterfuge and there are players who want to learn how to improve their Subterfuge game through learning new strategies. We should be careful not to solely focus on only one type because both parts are very important.
Overall, I really love this idea and would love to help in any way I can.
