yeah if this game gives you the option between stealth and action then great. but if its mainly stealth then i would lose a lot of hype for that

Might as well just make a movie instead of pretending that it will look like that in the actual game.

Samurai vs Mongol soldier !

Sounds intersting !

I think the gameplay will be quite similar, just without the extra shine cutscenes usually gain from the developer having more control over what's done and seen. It looks nice, but i'd personally say it's a slight step down from Horizon.

Hope stealth would not like AC/Mordor.

rewatched trailer.... hype rises!

also like the lore thingy about a samurai that throws away his honor, to do what needs doing by any means.
Turning him into some sort of avengeing ninja, trying to free japan by assasinating key targets.

I can't wait for story and dialogue in this game. Samurai certainly acted and talked strange so it's going to be interesting to control a character that doesn't show much emotions.

Yes, I'd say that's more likely. We need to take into consideration some of the core foundations of SP games though, and one is black/white, goo/evil with choice involved. Because the guy in the trailer says you have to know which villages to conquer and which villages to burn, I can't help thinking those SP core foundations are going to be involved somehow. 

Certainly came out of left field, but this is actually pretty close to one of the games I dreamed up as a kid. Should scratch that itch left by Way of the Samurai (and hopefully even Tenchu) quite nicely.

That doesn't necessarily have anything to do with the main character's actions, though.  Assuming the speaker was a Mongol, he is probably talking about their tactic of completely and totally wiping out some villages and cities while allowing others to remain relatively free as vassals.  It was their way of saying, "this is what might happen if you piss us off."  It gave them a steady source of supplies and soldiers, which they used to conquer more lands.  

I don't know if there is much historical data about it (in English) but I would guess that the game has the Mongols doing the same thing on Tsushima Island, with some villages burned to the ground and others spared.
