I was a huge fan of Sierra’s money-back guarantee. I can’t begin to imagine a software company standing behind their product so strongly today.
I think it worked in Sierra’s favor that during their glory years, a lot of families were buying their first home computers, and they often saw Sierra’s products used in demos. My father made a nice living building computers to order in the ’80s and early ’90s, and a Sierra product (generally the latest King’s Quest) was always the centerpiece of the “Look at the cool stuff you can do with your computer!” pitch. Although he wasn’t a software seller, he did stock Sierra games. They basically sold themselves. I’m sure that thousands of people across the country were introduced into the Sierra fold in a very similar fashion.
