I'm not keen on working in games professionally right now (though I wouldn't rule it out forever), but I'm still quite into game programming. I don't spend much time doing it these days though, since most of my limited free time lately is either on writing or programming languages.

But I'm still really passionate about the subject material (games and software architecture) and I think the book could be written, and I could write it. I also just really want to finish something for once in my life. Getting email from people asking me to keep working on it for two years didn't hurt either. :)

One little secret about the book is that it's not actually game-specific at all. Almost all of the patterns in it are equally useful in non-game software, but I think games are a much more interesting motivating example than yet another accounting application with EmployeeRecords and PaymentAccountTypes.

Thanks for sharing. Yes - games are a much more interesting subject matter than accounting records. :-)

I think it's a worthy endeavor no matter how it ends for you. You're contributing to the broader base of knowledge in the world, and clarifying your own thoughts in the process. Even if there isn't tangible immediate benefit to you, it's still a good thing to do.
