I've either DMed or played (or both) about 1/2 of these, and own most of the rest. Can't speak to Test of the Warlords or Red Hand of Doom (never had either of these) but the rest are all good except Dragons of Despair is, unfortunately, a Dragonlance module; and Dragonlance is a far better book series than module series.
