@Havenstone thanks for the thoughtful reply. I think you are right. I should start another thread dealing with the creative merits of IF as a separate, yet related, art form to standard fiction. I am well aware of the roots in paperback books several decades back. I am more concerned about the quality. I am coming from writing, not gaming or coding. Before possibly diving into this I want to weigh the time expenditure for non-writing functions versus the creative integrity.
The idea that fiction is co-created has a few problems for me. It would be like have co-created painting. An artist might make the sketch, then allow others to fill it in. This sounds interesting until you consider the skills and motivations of the other ‘artists’ involved. Or lack thereof. So in the end unless you have quality control of some sort you will get something that might satisfy the last brush strokes of the last person to finish the painting. But it will prove to be a pretty pointless exercise for the original painter who laid the framework. Likewise, if the characters are left up to the choices of whoever comes along they might not have the depth that the author might have wanted. Fine for a game maybe? But not for fiction. Anyway I’m going to think about it a little then come up with my new post. Thanks for suggesting that.
