For all the single player games I've played, even those that have an in-game journal, I've always kept a small notebook for the game with notes of things I want to get back to. It would be a nice "SWAG" to have a nice notebook included with the box that has a nice game art cover. A wonderful keep sake like my old journals I have stored as precious posessions. They will stay with me until they are handed down to my son upon the event of my death (he's in game design school now).
