Pam, I think it's pretty clear that your readers would be sad to see this story end. But the real question is, what feels to you like the right thing to do? Because you're the one who would be putting your time into playing the game and writing the story. If you think you'd be happy continuing on with the knowledge that this is an unofficial dynasty, that's what you should do. If you would find it more satisfying to know that at the end your DecaDynasty will be in the Hall of Fame, then I think you should cut your losses and start over. Either way, your readers will be here eagerly awaiting developments.
