Another thing we need in an anniversary package is a complete timeline. One that's a little more detailed than just what year a game takes place. It should include things like the exact year Lisa died, what year Alucard created the Alucard Spear, what year Ecclesia was founded, etc (and give Order of Ecclesia and exact year). It should also make it "clear" what canonically questionable items really happened. If it took place in an alternate universe, did it take place in a "connected" alternate reality within a consistent multiverse (like Circle of the Moon and Legacy of Darkness may have been) or a completely separate continuum (like Lords of Shadow and Legends most likely are). Include things like novels, pachislot games, etc too.
We got a timeline for the 20th anniversary, so its not too much to ask.
