Ah, too bad for the Epic Generator (and Boogiebac's hard work, of course), but something might still be salvageable. Based on my own experiences and what seems to be the consensus here, I would suggest you implement the following plan (the steps are listed in decreasing importance and estimated practicality) by:
1.) Shutting off work on the Epic Generator - as everyone has said, it will probably turn into a risky and/or costly logistical battle at the expense of other fun little features. It is a great idea in theory, and might be implementable in a future expansion or sequel, but we all (or at least most) would understand if it got set aside for now. You might also build the skeleton for it and leave players to fill in the rest, of course.
2.) Putting in a Data Log - something that could record the hard facts in the game, perhaps with a taunt or two thrown in by the AI

This would allow players to write their own stories, and would allow a lot more creativity in them.
3.) Putting in an Easy Screenshot Capture - some function and hotkey that lets you easily and efficiently take high-quality screenshots. A function that lets you organize them and/or add comments to them would also be appreciated, which leads into the next step ...
4.) Putting in a Photo Album or Storybook Editor - ideally, something styled after what is available in The Sims 2 and similar games. What I am searching for is a component of the game that lets you access the Data Log and Screenshot Log, and use them to easily create a story or gameplay example. The gameplay examples the Brad and others periodically upload are great examples of how this system could work: stories composed primarily of text but with annotated screenshots giving life to it. Giving us a relatively simple tool to do that would be greatly appreciated, and would go great with the next step.
5.) A Web database (or subcategory of the existing one) built specifically for such gameplay examples, or a forum or other medium made with accessibility first in mind.
Of course, I realize that the later 2 features might possibly take more effort than the Epic Generator, but they would be a great substitute for all interested parties, until technology develops enough for you to [realisticly] program computers to write "Epics".

Whatever you do, good luck, and know that you have my support!
