If you haven't played the first, do yourself a favour and play it before playing the second. That said, the vast majority of people interested in Bioshock 2 will have played the first, so it would be severely remiss to not compare the two. Players who liked the first will want to know how similar it is. Players who hated it will want to know if anything has changed. Now that's settled, and if you're still reading, let's carry on."
