I have only played Covenant of the Plume - not sure that falls in the franchise - and I recall that game was grounded in human politics and the exploring the personal stories of the characters one interacts with.
It seems to be a more personal journey as the characters that one has access to and what type of story arc one plays is decided by the decisions one makes through the story and having to weigh the value of human life against a backdrop of colourful characters.
Seems the games are similiar in concept and design with some differing gameplay mechanics
Seems I got a fairly good idea from your answer and OPs post.
Seems VP1 is more optimistic in its outlook by comparison as your companions seemed to have already been qualified to be tested to join the ranks for Ragnarök. But seems to place more value on an individual character as it has effect on the meta-narrative value.
I do know that CotP deals with some pretty heavy topics of the reality of the period and I did appreciate that rawness to it as it helped sell the setting and provide sufficient investment to see how far the rabbit hole went.
