The introduction of PS Plus' tiered service (Essential, Extra, and Premium) has made for a couple of exciting months on the service. There's something about the constant influx of games and information that keeps the service in mind much longer, as Sony reveals the Essential games, releases them, reveals the Extra and Premium games, and then releases them. It's hard to say how this PS Plus tiered service defines the company in the future, but it's off to a great start.
