At my first job out of college at Wizards of the Coast, game designer Jonathan Tweet taught me that for any game project, you should try to write the back cover sales text early and revise it often. You may not ever use that exact text for real. But by thinking of your project in such concise, player-facing terms, it really helps you focus your thinking and cut what should be cut. I’m still using that advice today and it’s more important to me now than ever.
