Good grief. It would be more than a little presumptuous for many of us to try to answer these questions. These are questions that could best be answered by Ken Williams. Even today Williams (though busy with many other things) remains remarkably accessible for fans when he is able to participate in the forums at SierraGamers.com, is forthcoming about his Sierra years, and is also supportive of new adventure game projects. I just want to say right now that the man is a genius. You don't remain the undisputed leader of an entire industry for as many years as he did and not have some serious skills.
To try to answer your question, though, Sierra seemed to rely on the KQ series to introduce new technologies and design features.
By the way, who isn't interested in monetary success? And didn't the very survival of Sierra at one point depend on the success of KQ1?
