This game could definitely benefit from a little more exposition. The grimoire cards just don't do it. Maybe have a "librarian" in The Tower who lets you peruse materials (think the card info but actually in game). Still, nobody bothers to tell the Guardian anything beyond where and what. Never why. Like when you get to Mars, it's "go break through the Cabal's exclusion zone". Well, who in the -blam!- are the Cabal and why do they have an exclusion zone? A little cursory info here and there would be nice. Sometimes having "less is more" works, lending to mystery. Yet here we're at so much less that we're just scratching our heads. Of course we're gonna shoot the aggressive aliens. We don't need to entirely understand them. But a little rundown on our key players from the Ghost would have been nice. Now on the other hand, hopefully we get the rest later. Halo:CE did that if we remember. No real explanation in the first game, just the Covenant attacks and we go from there. Zero explanation for what the Covies want, just deal with them. Granted, Cortana was always more talkative and freely shared with you the reasons for every objective. The sequels did give us info though, the Prophets' religion and so on. I'm hoping Destiny will do this in game as more content drops.
