Our senior backers ($20+) have the opportunity to individually propose and then collectively vote on an idea for expanding the game, and they can do this every month - everything you see as "Dreamweaver choice" in the changelogs was created this way! There are some restrictions - they have to be practical, consistent with our current canon, use our existing characters, etc. - but it's a mechanism that has given us a lot of great stuff over the last couple of years :)
