How do you make a hit game? Here's an essay by Tony Downey that comes as close to a recipe for success as I've ever seen: Indie Games: Designing to Succeed. READ IT. Following his advice is going to be very hard work, but making your game without following most of this advice will be just as hard work, but you'll make less money. This essay is BRILLIANT, thanks Tony for putting this together for all of us. For more advice, check out my book reviews for books on game design and books on app marketing.
