The pro's and con's of the Fortress.

Being the best defensive town in the game, the Fortress is one of the better towns in
small maps.  The large moat and the defensive structures that can be built along with the
huge Defense skill of Fortress heroes (and creatures) make attacking a Fortress a very
difficult task.  Combined with the fact that Fortresses are located in swamp regions (very
slow movement for enemies) it is not hard to see that Fortress heroes have a big
advantage in small maps.  The creature ranks however, are completely disorganized.
With one weak ranged attacker, 2 flying creatures and no fast cavalry-type creatures
Fortress armies are too slow to be blended.  In small maps the huge amount of Serpent-
Dragon Flies, the powerful Basilisks and Gorgons are very capable to crush your
enemies.  In other maps, Fortress creatures lack the speed it takes to create an
offensive army.  Tactics and Ballistics may help to augment their combat value, but even
then it will be hard to complete the map.
