I admit there's a small place in me that wants it to be a incidental clusterfuck. Like I love the idea that Mitsuhide looks over at the temple, remembers his poetry getting trashed and the good dinnerware getting chucked in the pond (and you know his mom dying) and just goes "I'm setting this son a bitch on fire".I feel like Mitsuhide is probably the natural antagonist for this game but because his real life motivations for betraying Nobunaga are still just about ambiguous enough you can take him in many different directions. AssMemories generally aligned the Assassins with Tokugawa (an interesting but kind of cynical writing decision probably based on Ieyasu 'winning' in the end lol) but it seems kind of unlikely that they'll bring back, say, Taka or his storyline for this game. A mainline title release will basically forge its own path, though I could see a Sword of Eden being relevant to the plot.
The templars and assassins are having a face off and then one goes "Guys did either of our sides set Honnoji on fire? Cause it's very on fire right now".
