Diablo II is a click fest. I haven't clicked buttons so fast since I played Track and field on the original Nintendo. In fact, I strapped a set of battery powered chattering teeth acro the left button on my mouse and, by the time I got back from seeing X-Men at the local cineplex, my system had already completed the first two scenarios.
In a Strategy game, clicking is set to a minimum, and every now and then it lets you click AND drag!
