Setting up referral rewards for backers?
I guess the con that I see, would be that the referrer might not know who got "convinced" by him, especially if he spread the word via a general facebook share. An alternative would just get referrees to state their referrers, and not require it the other way around. Hm.
What should these rewards for a wilderness expedition cost?
If you're concerned about people using your work without your permission (and that is a reasonable concern), you should include a short statement of copyright with the downloads, including a copyright bug: "copyright Aiden Hall 2018", etc.I think it's wise to include a low-amount pledge, but at the same time, don't undervalue your work. With a project like yours, I think you'll be getting support from people who are willing to support a project that sounds like a cool idea and could turn out well — like traditional patrons — rather than consumers looking for value for money. I wouldn't start any lower than $5 or maybe even $10. Remember, Kickstarter will charge you a slightly higher cut on pledges less than $10.Good luck!
Do you feel that a creator ranking system is necessary?
I see two possible issues:1) It would be reductive, taking a complex web of data and expressing it as a simple series of ratings. Your own post correctly identifies, I think, that assessing creators involves a lot of nuanced judgment about what gets said and by whom. Aside from whether or not a creator delivered on time, just about all of what you describe are subjective criteria and therefore you need context to make proper sense of them.2) Because of that, I predict that such a system would be subject to the most ruthless and destructive kinds of manipulation, and creators getting distracted by wanting to pump up their own rankings. In other words, something as sordid and ultimately useless as eBay's feedback system. I can certainly see competing creators trying to sabotage each other because (as on eBay) every creator is also a potential backer — maybe not in the gaming category where (I like to think) creators often know each other and support each other, but certainly it would happen.
