Open development is just about the worst idea for games.
People like to think they’re pretty special. And people do tend to have a habit of thinking what they think is right, and those who disagree are wrong. In my case it’s actually true, but unfortunately that’s not always the case for others. And really, honestly, the very last thing I want is other wrong people to be influencing the games I’m going to play. Developers have to stop asking other people how to make their games.
