Play is the point. Become an expert player.
Here’s how you contribute: you play a variety of games. You go play Dust Devils, and Trollbabe, and Dogs in the Vineyard, and Universalis, and My Life with Master, and The Pool. You play the hell out of them. Then you make something better, later, when you’ve played these and you know exactly what you want. Or you don’t make a game at all – even better. Play is the point. Become an expert player.
