One vital thing to designing great games: Don't forget to get away from the project. There are amazing experiences outside - new scents and sights, colors, sensations, styles, spaces, perspectives, people. There are opportunities and possibilities you can't imagine until they happen. We live inside the most complex procedural generator in the universe. There's raw inspiration all around you, right beyond the doorway. If you want other people to feel, feel yourself. Expose yourself to a breadth and depth of emotion. Create vibrant memories you can call on in your design. I spent the weekend offline, consumed by feelings I could spend the rest of my life trying to capture in a game. Up and down, better or worse, depression and euphoria. This is your one life. Live it.
