The final insanity is the sum of Dragon Commander's parts. Mashing together genres is as dangerous as putting a jetpack on a dragon and hoping everything goes well. If it works, you'll have the full experience of being a leader in an ancient part of the Divinity universe: diplomacy, economics, political wives, territory control, direct command over individual battles, and participation in those battles.
