In fact we say Serbs because it is his Serbia campaign but it was actually Hungarians he was fighting against. Serbia was a vassal of Hungarians,
anyway just wanted to clear that out.
Mehmet wasnt victorious in his Serbia campaign. He wanted to conquer Belgrade, he got wounded and the siege was cancelled. It was conquered in the period of his grandson Suleiman I.
Mehmet wasnt victorious against Vlad neither. I mean he politically was but not militarily. Vlad killed his ambassadors so he marched on him. On the way first Ottomans suffered a night attack and many casualties then as they marched to Targovishte Ottoman army witnessed the terrible sight of their impaled men. He considered turning back.
Then Vlad was betrayed by his boyars and his ally Stephan of Moldovia who promised to help him, seized the opportunity and attacked him instead. Vlad escaped to Hungary and died there.
So there is no military victory here to make a campaign about.
For the Otronto, you said it yourself. It wasnt his fault bu regardless, Otronto couldnt be defended and it fell back to Italians. So why would such an indecisive event be ‘‘so great’’ to be put into the game ?
Conquest of Trebizond.
There wasnt even a conflict. He surrounded the city and David surrendered.
apart from these, he suffered terrible defeats against Albania and Moldovia. Go read battle of Vaslui. It was a disgusting defeat.
Overall Mehmet 2 had two very important military victories conquest of Constantinople and battle of Otlukbeli against aqqoyunlu. I think if they are going to do something they should add ‘‘conquest of constantinople’’ as one single battle instead of a ‘‘Mehmet II campaign’’
