Skillshare - Need to Knows about Game Design

In "tip form" and "list form", this is a summary of what you need to know about efficient game design and about designing good games. It is about as much as we can squeeze into the short Skillshare format. My main game design class, not on Skillshare of course, is about 13 hours of video (not counting the bonus material), the equivalent of a book. We can only get started in 50 minutes.
