Initially it was the immersion that always drew me to games, the idea of a whole new world to explore and characters to meet. Later it became the experiences that truly stuck, and I constantly think, “How does each level and mechanic impact the player experience?” When I design maps, or mechanics and items, I imagine how players will interact with them, and the memorable encounters I hope they will have. When I finally give a friend my game, it is their response, the story they’d tell of their experience of putting a golf ball into a black hole, or seeing a character spiral out of control, that gives me greatest satisfaction.
