[General, Interactive, Philosophical]
Maybe I'm still getting over the fact that Homestuck has ended, but I've always wanted to try an interactive story like that, albeit much shorter.
This is where everyone else comes in - the readers may chose what the protagonist will do! I've given options (A, B, C, etc) that they will vote on. The last choice will be blank, letting anyone comment ">D. _____" with whatever command they wish.
