Hey Bungie, I've had a great idea you could use for the grimoires that would greatly increase players will to do quests and kill certain enemies. If any of my fellow gamers out there have ever played some of the old Final Fantasy series. There was a card game built into the games where monsters would drop cards and players could have card games vs AI opponents (Yes I currently forgot the name but you get my point). Now looking at the grimoires they resemble cards even with images, and some even looking like spell cards, Turning the grimoires into a card game built into the game with a reward system for players that gain enough grimoires and complete matches would give players a great side game or side goal to playing destiny. I could be mistaken but at the moment there is zero use for the grimoires other than reading some story info.

Might make for an interest mini-game and would provide the current cards a better value to the player.
