Maybe it's more academic than practical to say so, but Ludology and Narratology and all other studies and practices into the nature of play intrigue me. That's actually putting it mildly. Most of my free brain-space is spent designing puzzles and mechanics and stories. I think that's what people mean when they say they've found their dream. To all budding game designers in the world, read Charles Bukowski's poem "So You Want To Be A Writer" and just replace every instance of "writer" with "designer", and "words" with "mechanics", and "libraries" with "audiences", etc. because this business can't handle anymore careless designers. Goddamn, I want to see the medium improve in it's ability to enrich our lives, and I want to tell my stories. The work can be frustrating and difficult, but that's why I have Mario to remind me what to do. Just keep running in the right direction. You may have to start over many times, but you'll just keep getting better.
