“Design pitch tip: “I’ve spent X years developing this game” is a red flag sentence for many reasons. It doesn’t help your pitch.”

— Nate Murray

“You’ll make a game and think you’ve nailed it the first time you write the rules. Then comes the real work, which can be exhausting, discouraging, confusing. But if you believe in your game, don’t be dismayed. Get it in front of people. Playtest it. Toss out what isn’t working, explore new ideas. Make something you love playing, and then enjoy what follows.”

— David Somerville
