A TBS with a sense of humor doesn't come along every day. Don't mistake light-hearted for light-headed, however - "Warlock 2: The Exiled" is a solid, if limited, game. It can provide hours of fun in an attractive package without overwhelming the player with detail.
In summary, if you like GalCiv3, you will like this expansion. The primary problem with it is simply the lack of new material. Other than the Bazaar, this has the feeling of a well-done couple of DLCs. Not really worth the 20 bucks except for fans of the series.
