One thing you should know up front—writing Blizzard game previews isn’t easy. Wax too ecstatic and you’re a fanboy, come down too hard and you run the risk of looking like an idiot when the game ships with none of the bugs and flaws you identified. The game itself becomes a moving target, with characters and game mechanics modified in each patch. Your impression of the game, therefore, is less a statement of what it is than what it was, and identifying the core components that are likely to carry over in the shipping product isn’t always easy, especially if the company in question is willing to take chances and try new things.
