“I can summarize good game design in three words: incentivize interesting behavior. A good game designer figures out fun behavior in their game and steers players to act that way.”

— Gil Hova (@gilhova)

“I think probably the best advice I have is work on distancing yourself from your project. Be willing to break it and re-form it and think of it as an object distant from yourself. Be willing to push, and bend, and break that thing, and be focused on creating the best experience for the gamers and understand that it’s something you’re making for them.”
