Before I even get into the suggestion, I need to say I love the game. The world Bungie created is amazing and so far they've given us the intro to what I think will be an amazing story. I believe Bungie did this on purpose to A ) let the player make their own assumptions and theories about what the future may hold in the Destiny world and try and fill in the gaps to tell their own story (thus every guardians story is slightly different) and B ) to tell a story over years instead of the months that most games have for a shelf life. As for my suggestion about the Grimoire, as much as a I love the story and lore behind the Destiny world I think it falls short on delivering that to a large segment of the player base by having it separate from the game. I realize it's probably a marketing tool to try and get players on Bungie.net or downloading the companion app but I don't think it has worked as well as Bungie intended. The Grimoire really should be in game, as a long time player of Mass Effect I'm picturing something like the in game Codex that was in all three Mass Effect games. I even have the perfect voice actor to use that would people would love, Keith David. His voice with an in game Grimoire would definitely get people to become invested in the story and lore of Destiny, which seems to be greatly needed to get more people to appreciate the game itself. If you're unfamiliar with the Mass Effect Codex here is a link, it's over an hour long but you can get the jist of it from a few minutes. https://www.youtube.com/watch?v=oeL6tis2qr8
