Games like this have to charge an actual price. They just have to, if the developer wants to stay in business. Why? Because if I charge a dollar for one of my old school role-playing games, even if everyone who could possibly be interested buys one, I would go out of business. So I have to charge more. Games in this category will be five dollars minimum, possibly more, and if you complain that the price is too high, that is like saying, “I want you to go out of business to please me.”
But then there are niche titles. Games for gamers, or games aimed at a smaller audience. Adventure games. Strategy games. Games like what I write: old school, low budget role-playing games. Games like this will never have a huge audience, and they aren’t trying for one. They are aimed to serve a small, dedicated audience.
