Of course only the release of the game will prove me wrong or right. The gameplay you posted looks extremely boring and repetitive to me.
I won't say again what I said in the first pages of this topic: it's Assassin's Creed/Batman in a LOTR setting with the only one new thing added to the mix being the "nemesis system".
I don't expect this system to be interesting: it is meant to make place for replayability -- however this game's combat system becomes redundant and boring really fast, I'm not sure I would play this game more than once. The developpers should never focus on replayability in my opinion. Make the game good, enjoyable and diverse, well-paced in the first place.
Also, I'm not sure you can make Batman/AC combat system anymore. Let this to the said franchises and try to make something a little bit more interesting and innovative, please.
I compare this game to Titanfall because Titanfall was a boring, well-crafted game without surprises and ambition, with mechanics I already know, in a setting I'm familiar with. The way mechs are implemented in the game is the only thing worthwhile (but nothing original by itself, I agree).
SoM has a setting (and even characters) I know, doesn't look bad (the world map in the vid was kinda bland though), seems to have mechanics I already know. Looks like the developer took 0 risk in making it.
