I think most of the guards had pistols. They would randomly pull them out in battle like the Redcoat captains did, literally like the same animation and the same move to use a human body shield, and despite their semi-automatic pistols they would only fire one shot lol
I lold at this idea.
Hopefully you got a chance to read my post with the spoiler thing that I responded with.
The cool thing about the Assassin's Creed games is that they create this realistic world and you get a feel for how people used to live. Just by exploring the environments, you don't look at the past the same.
I think it would be cool if Ubisoft ended the series at AC4, and their next game had you playing as a ninja. Cliche? Maybe, but they could set it apart from other ninja games quite easily. They could mix elements from the AC games with brand new elements. Ninja's were often farmers and peasants, so there's your stealth mechanic. During missions where you wore a ninja outfit, you would have to actually sneak around instead of blending with the crowd. They could add a mechanic where Ninja outfits granted improved movement speed or harder detection. Of course, while wearing the suit, everyone knew you were a ninja and would pretty much kill you as soon as they saw you.
The thing is, there's so much we don't know about ninjas. There is so much myth mixed with fact, it's hard to tell what they may have really been like. It's said that was the ninja's plan, to create myths to help confuse their enemies. They could make it so you felt like a real ninja, rather than some sort of super powerful fictional character.
I don't know, it's just something I wouldn't mind seeing, even if it is a more generic theme.
