My theory is based on WoW being categorized as a “New School `Casual Friendly` Slayer.” Those games suffer from longevity issues, and World of Warcraft is no exception. I consider those games little more compelling in the long term than Diablo II. World of Warcraft’s excellent sales figures do not impact this, because when Diablo II was released, I’m certain it flew off the shelf just as quickly. Like World of Warcraft, the number of people playing Diablo II could have been counted in the hundreds of thousands. How many do you think are playing it now?
