Nice_Boat: I know this thread has a lot of months on his back, but, could you please tell me what's that new feature?

-New Extreme mode which covers over 10,000 units on the battlefield
-New buildings (outposts generating attacking enemies)
-New tactical special powers (reinforcement, field hospital, rock volley attack, arrow volley, engineer team, macemen squad, uncover gold horde, call for knights).
-New Crusader Extreme trail with 20 linked missions as well as new stand-alone maps (for single or multiplayer mode).
In addition, Stronghold Crusader Extreme features new AI previously obtainable opponents (The Wazir, the Marshal, The Emir, The Abbot and The Nizar from Stronghold Warchest edition).

Anyone can confirm if GOG version have this or not?
No, it doesn't.
The mentioned AI players are there, but that's because it's the Warchest Edition.
