Sound is average. It lies somewhere below memorable, but doesn't really detract much from the game. The single player campaign consists of 48 scenarios that take place over the course of a Great War between the kingdoms of Darien. In between the campaigns, you are treated to small movie shorts narrating the major events of the war. Because you switch sides from scenario to scenario, you will, ultimately, experience all sides of the conflict.
Kingdoms is played almost entirely with the mouse, and a few simple keyboard commands.
None of the game's commands cannot be accomplished by a simple point and click. Kingdoms looks good, sounds good, and tells a good story, but, unfortunately, it lacks teeth. Of the 48 scenarios, a surprising number of them simply aren't challenging, and a few of them are downright silly. Though I don't mind acting out the major events of the war, there are some parts of the conflict that I don't need to personally experience. For example, at one point the kingdom of Taros orders the assassination of Aramon's chief alchemist.
