First Draft: Committee for the Exploration of Mysteries...

I've got a nearly complete draft of my pulp-genre entry available . I still have some examples and a rules summary to add, but I'd appreciate any comments, loopholes noticed, etc.
A question I've been mulling over this morning: How long do you think it will take to make characters, collaboratively create an exploration site and route, and bang around ideas for hazards and have each player make two lists of them? Is this enough for the first three-hour session, or will the players have time to get a round of play in too? Of course, playtesting will ultimately answer this question, but no time for that this week
Thanks in advance for looking it over.
