Okay... first off, combat-wise it looks like what Assassin's Creed has been trying to do but failing a lot. By that, I mean in Assassin's Creed games there's usually a pattern when in combat and that kind of well, takes the fun out it after the twentieth fight. Also, the whole fixation of slow-mo after killing the last enemy really detaches the gameplay, kind of like the pause effect in the recent 2D Mario games when playing multiplayer. In this game, it appears to use similar things, but lets the player control everything. In a way, the Batman Arkham games, Sleeping Dogs, Remember Me, and even Sly Cooper - starting with the second game - lets you have a much faster paced combat system while still having an instance, the point when the game switches from free-roaming to combat.
Also, the game allows you crouch which for whatever reason, Assassin's Creed never had as a normal ability; you could only crouch in bushes and through a "special ability" in The Tyranny of King Washington. Really?
As for the character having another being inside him. This reminds me of the cancelled Legacy of Kain game, Legacy of Kain: Dead Sun. The main character was a new type of vampire, the Saradin, that feeds on souls instead of blood and through a freak accident, has his soul and mind as the dormant personality of the human he fed on, Asher. So, the game was supposed to have a human's perspective of a strange new world aided by his unlikely guide. It was also supposed to be on the PS4. Unfortunately, like all the previous attempts, it was canceled.
Anyway, on voice cast: Ratbag sounds like he is voiced by Steven Jay Blum with an English accent - can't say where in England. And oh great, Talion is voiced by Troy Baker. I guess he's going to be this generation's Nolan North. Come on developers, if you're going to use Troy, Nolan, etc., have them do more unique voices than typical hero Troy Baker and average guy Nolan North. At least Troy's role in The Last of Us and Nolan's role in Spec Ops: The Line and as Deadpool did something different with their natural voices. As for the Wraith, I don't know, but I wouldn't be surprised if it's Troy Baker using what he learned as Young Joker in Arkham Origins - now that's using his talents - to create a twisted, interesting, and memorable character/voice.
