I've been playing for a while this game (Completed Dead Man's Switch, now running through Dragonfall and enjoying it a lot more) for a while now and I'm noticing that... well, the game seems to be designed for people who actually know a bit of the Shadowrun world.

I can get/figure out some of the lore behind the game, but the lack of books/magazines and other content in game to read about it makes me think that I'm missing a LOT of the fun in the dialogues or other references (Or even things that seems to be "common knowledge" for the characters in the world, like that thing with Dragons being CEO's of the big corporations).

So, any suggestions in what should I read to get some knowledge of this world?
