Great quote from an old Forge post on Non-linear play in which the GM started the game with the last scene and then jumped 96 hours previous.

There has to be some rearrangement of displayed character traits. One character, in the final scene, claimed to want the “BIG EVIL” dead so badly he was willing to sacrifice the whole of Del Ray Diablo to accomplish it. When we flashback 96 hours, however, he has a family, a job, and is generally a nice guy (he coaches his son’s softball team).
I see it as my job to help engineer the change… and I think it is fairly obvious how I will be going about this.

Heh. Hheehehehehhehh. Heh.
