Indie games these days are really innovative and often cross genre boundaries. It would be nice if I could choose more than one genre for my game. I know I can pick one and use tags for the other, but that seems like it will arbitrarily segregate my game into one category or the other, rather than allowing it to be discovered through either. Of course, folks could game the system by assigning all the genres to their game so that no matter what you search for, it pops up - so maybe limit it to three genres per game? That should be enough for even the most innovative developer!

Tags and genres are actually the same thing in our backend, so you can already use multiple genres through tags. The Genre input on the project edit page is just a special tag field that shows only the genre tags, and also lets you assign 1 additional tag to your page. We do that to encourage people to at least fill that out, because often people will ignore tags or not filter through them to find what’s appropriate.
