First I shall apologize: I hope you didn't perceive my comments as disrespect to all the effort that people put into this project so far. It's a great project and it seems to have progressed very good. So my comments are not critiques, they are my concerns on how I believe this project would be even better. I would feel really bad if you think "Hell, who is this guy? He's falling from the roof into this forum and thinks he can give us advise?"
I see what you mean with "secret" and why it isn't possible for an "open" project to keep things as a "secret". But you say this from a "community" or "designer" perspective, isn't it?
I am speaking of a "player" perspective. The person I have in mind is someone who downloads the "finished" game, installs it and starts to play it. Now the question is, what is the best way to lead the player through the story that we as designers know all aspects of, but which the player has to discover and figure out step by step? All my comments are regarding this question.
I'd like to give this example: If we write a detective story, we know the whole plot of the story and who the murderer is and why he did it etc. But we would keep the murderers identity as a secret until the end of the story and make it the goal of the detective to find out. We would mislead the detective (and readers) by introducing bits of new information that result in a theory on what happened. But then we would introduce additional information that cancels this theory in order to maintain the mystery. For example I'd let the autopsy expert say that the the victim was killed by a left-handed person and voila, during investigation of neighbors our detective would toss at a left-handed man... who had an argument with the victim a few weeks ago. But just a minute later the neighbor would introduce his girlfriend... which is left-handed too... and who, so it turns out, is still the wife of the victim etc
So I am talking about a knowledge regime for the story, of creating point-of-view, mystery etc... not about the knowledge sources that the open source community naturally must have access to in order to realise this project.
As players, when are we going to find out that the Aliens already have conquered other planets? When are we going to find out about the mothership on the dark side of the moon? What impact will these bits of knowledge have on the players perception of the game. Is there a better, more shocking or intriguing moment to reveal this info? Is it relevant info anyway, e.g. does it succeed to elevate the story on a higher level?... Things like this are my concern.
