Good point, I will try to also make a blog post about that. I think that the way I do things is counter to "good business" for a lot of developers, too -- publishers want you to be done with a game in a few months, so you'll buy something else. In our case, it's more about word of mouth. And, of course, it's nice if people go for the expansions, but that fits in with extending longevity rather than causing players to move on.
