Sequels generally have a handful of references to their predecessor, or at best, the story continues from where the first one ends. Mass Effect 2 has scaled new heights by incorporating a seamless continuity if you import your saved games from Mass Effect 1. The actions from your past dictate your experience in the second coming talk of Karma. However, if you haven't played the first part and have jumped directly to this, you won't die wondering what's happening. Bioware takes the liberty of dictating your past decisions."
