How about releasing ONE finished scene so people can see what they'll be getting?
Honestly, if you really want donations, keeping folks in the loop and showing them bits of the finished product is a good way to entice them. I asked my question originally because I was tempted to donate and wanted to know more before I did. Several other posters also liked the idea of a progress report, maybe they were thinking of donating too.
Giving us a heavy, condescending attitude is probably not the best way to fish for cash.
