I think you get something in the second game after you play the first, but I forget what. It's not necessary though. B2 features new characters that you play as. The characters from the first game reappear as NPCs which is kinda neat. It's like B2 feels like a totally new experience, but some of the characters from the first game are arround to remind you it's the same world. So it's totally not necessary to play the first game first. It's not like Mass Effect where you can carry over your character or anything.
