City Hall designer Michael R. Keller (@vhgames) discusses gut-wrenching decisions, low downtime, juggling multiple projects, market mechanics, humility and more:

“It is valuable to have several games in development simultaneously to avoid getting into a design rut. If one game presents a persistent problem, you can set it aside for a while until inspiration strikes.”

“The first time you think your game is done, you’re wrong. The next hundred times you think that, you’re still wrong.”

“Don’t ever dismiss a playtester’s feedback. You may know your game better than the player, but the player knows what it feels like to play your game better than you do.”
