Great thread! Haven't had a chance to read over all of st0ven's stuff yet, but one comment for FaeryShivers:
I don't think that the person with the design vision should necessarily be the project leader. Project leadership requires a lot of extra effort and leadership skills that a good designer isn't always going to have, and requiring them to both design, do their normal work, and lead, could be a pretty significant hindrance to your project - I've heard stories of this being a real problem in both large-scale commercial development and indie development.
You're right, but its an easy way to ensure the game vision stays in tact on a smaller team where there is not much money
to influence people to follow the game design and not try to "overthrow" the project with their own beliefs so to speak.
If you know someone who is a great leader and is dedicated to keeping the original game idea intact thats great. Its just really hard to find that on a smaller team especially one without anything to keep peoples minds focused, IE an income. As sad as it is, almost everyone has a price at which they will accept money in exchange for their time without question as to what they are doing.
It is harder to keep volunteers from wanting more control of the project as they do not always feel they are getting something for their time.
On more than one occassion I've had people quit just because they assumed that because we did not change the game the way they wanted to every time they made a suggestion, we were not listening to them. People will often also quit a free project if they cannot do as they please as once again they feel they are not getting anything for their time. Its more common with programmers than artists in my experience but it does happen. Beware of the person that assumes that because you do not do exactly as they say all the time, you are not listening to them. Especially if their ideas are usually ones that would completely change the way several systems work.
Please don't get me wrong here, volunteers are to be appreciated but, there are some people who get onto a game team with an agenda that was not disclosed immediately
