Seems to be a little bit more Corypheus content if one takes the Templar route in the game. Just finished the Temple of Dumat and I am going to have to read up a little more on this Calpernia as she seems a really interesting character. A tad more interesting than Samson.
Vikings is a terrific show. It's historical veracity is a bit dubious but the show is really done well and works as entertainment. Looking forward to the new season!
Yeah, you definitely get more on Corypheus with that Calpernia quest, although the whole crystal recording device thing was a tad out of place to me...but I let it go..
Samson has more ties to the previous games so you get to see the fulfillment of that original arc, but there isn't as much to him, at least so far in my 3 play throughs, as there is to Calpernia.
That is one thing I Like about the choice between Mages and Templars..its not like just replacing one sub villain for another, it does actually change your game experience a bit, you get things with each that you dont' get with the other.
