2) If you have an idea for a game, and you’re looking for a publisher, understand that publishing is a lot of work, involving a lot more than just an idea and a printer: it takes immense amounts of coordination: design, testing, sourcing materials, sales, and of course marketing efforts to get consumers to want to buy your game, not to mention convincing stores to even make it available to the consumer. This is my favorite essay on that topic.
