Having beaten this game, and all of the DLC, I can strongly say that this is among the best written game series that I have ever played. The characters are well developed, the score very well done and placed, the dialog very well written, and the ending exceedingly perfect. You are missing out on a lot of the story, if you do not play the two Burial at Sea additions.

The not being able to save bothered me at first, but I found that it actually helped to keep me from forgetting important immersion points, from how it begins each chapter. The method is actually an improvement, in my opinion, as opposed to the save anywhere option. The challenging difficulty was fantastic. I had immense trouble at some points, making it require actually strategy, instead of just banging your head against a wall until you get through. While that might work at times, and the Clash in the Clouds addition does feel like that, this game benefits the person who uses a methodical approach, rather than guns blazing.

I have read some have become of sudden experts on quantum physics, and they dismiss the ending of the main game. From Doctor Who, Star Trek, Time Machine and many other movies who have done such ideas of paradoxes, there is no straight answer to how it could or could not work. I did feel a bit at odds with the ending, despite it being very well done from its own individual point, but having playing Burial at Sea 1 and 2, I can now say the writers of this game, and the additional content, are simply amazing.

While I hear rumors of a fourth addition to the Bioshock series, and I hope that it does come to fruition, this series could end respectfully here.

In short, this is a must play game, if nothing else, for the story. You will need to have played the first Bioshock to get the fullness of the story, though Bioshock 2 is just filler, it is a worthy part of the series as well, if you enjoyed the first and third part of the series.
