Bioshock 2 had some huge footprints to follow from the blockbuster that was the original Bioshock game. Fortunately in my opinion, they succeeded. Now that does not mean this is just a continuation or a little different story than the original Bioshock, in contrast that is the reason why this game is great. Bioshock 2 developed its own unique story line while at the same time keeping the original story in tact. Most sequel games fail at this, like Halo and Far Cry for example. They just feel like the developer is trying to cash in on previous success. Bioshock 2 is not one of those games, it seeks to gain its own merit for being one of the best role-playing first person shooters separate from its parent Bioshock.
