Addendum

As for alternate history, I'm not sure that actually exists in our timeline, probably because the Battle of Stamford Bridge turned out the way it did. I don't need to tell you the outcome, same-timeline buddies. Obviously someone whose name begins with "Har" won.

The Latest Release

Aside from anything else, is Assassin's Creed: Shadows a good title? It doesn't tell you much, not that many of those titles do. Odyssey, Valhalla, and Black Flag give us a sense of the setting, which is why I can remember them. I'm not sure it's important that we remember them, but the real problem with Shadows is that it sounds like it could easily be a spinoff, possibly a mobile game.
