I'm trying to learn about applying agile methodologies to game development. But seems to be impossible to find real life examples.

There seems to be plenty of material discussing how 'in principle' agile is applied to a game. But that is NOT what I am looking for. I have the Keith book.

What I AMlooking for are real EXAMPLES of things like;

1. Initial user stories
2. Final user stories (complete, covering the entire game requirements)
3. Acceptance criteria
4. Task list
5. Sprint backlogs (before and after each sprint)

The agile books seem to have some limited examples, many of which seem contrived or limited. In this era of open source software, there must be a publicly available documented example of the process applied to a real game.

I am asking specifically about games because they are so different from normal applications. Regular applications are built to all users to complete specific tasks in order to get stuff done(book a room, print a report etc). People play games for much less tangible reasons, so I think the process is significantly different.

[it doesn't have to be scrum, it could be any process, just needs to be a real life example game and be reasonably complete]
