The waning days of summer are upon us, and for the first time in six years Microsoft hasn't kept the release schedule moving with its annual Summer of Arcade promotion. Part of that is no doubt due to the promotion's title. It's named after a delineation between downloadable "Arcade" games and larger retail games that Microsoft readily acknowledges isn't as relevant in the modern market. However, this summer passed us by without any similar promotion, even as Sony continued its PLAY program. Why? We can glean part of the answer by looking back at how the promotion developed over the years.
