[A possible spoiler for players with not completed Stronghold 3 Campaign] -------- First of all, I was sort of surprised by the ending cinematic in military campaign, how The Wolf captured the main character (and presumably killed him seeing as he said it earlier he is going to do so). It itself just suggests that Duc Volpe may be our 'playable main character' in the next Stronghold, wouldn't that be sort of 'innovation' for Stronghold series? Playing as the 'main antagonist' changes the campaign perspective completely... But that's just my way of thinking - do you guys think Firefly will let us play as Wolf in next Stronghold?
TL;DR - Duc Volpe (The Wolf) as a playable main character in the next Stronghold, well - at least there's a possibility
