Probably on of the most creative games out here, a sci-fi game that does not need Space, aleins, or marines, with a unique setting and story.
Story
"I am Andrew Ryan, and I'm here to ask you a question. Is a man not entitled to the sweat of his brow? 'No!' says the man in Washington, 'It belongs to the poor.' 'No!' says the man in the Vatican, 'It belongs to God.' 'No!' says the man in Moscow, 'It belongs to everyone.' I rejected those answers; instead, I chose something different. I chose the impossible. I chose... Rapture, a city where the artist would not fear the censor, where the scientist would not be bound by petty morality, Where the great would not be constrained by the small! And with the sweat of your brow, Rapture can become your city as well."-Andrew Ryan
The story is about you, Jack, after being the only survivor on a mysterious plane crash you see a strange tower in the middle of the Atlantic ocean, it is the only structure there and you must board it to survive. You are then taken to the amazing city of Rapture, underneath the ocean, allowing "No God, No Kings, Only Man".
The city has gone through a catastrophy, and is a large dystopia now, under the iron fist of Andrew Ryan. Through out the game you are sent on quests by a man named Atlas, doing tasks for him and Tenenbuam, fighting things from horribly spliced humans, to a Big Daddy here and there, and rescuing or killing Little Sisters, you must kill the tyrant of rapture who holds the town in an iron fist. Of course you are not without defense, you have your conventional guns and a melee weapon, but you must also take some of the splicing material, called ADAM, this rewrites your genetic code to let you pull off amazing abilities from firing electric bolts to setting people on fire, these powers are powered by EVE.
There is a moral choice system in the game that is picked depending on what you do with the Little Sisters. Rescuing them will get you less ADAM, but you get a reward of even more ADAM from Tenenbuam, this will also unlock the "good" ending. The "Bad" ending is unloacked by Harvesting the Little Sisters, this gets you more ADAM, but kills the Little Sister.

Gameplay
"A man chooses, a slave obeys."-Andrew Ryan
BioShock has elements from shooter, RPG, and minor Puzzle based genres. Shooting is revolved around the gunplay from various guns you find and the ammunition you find for them. Next is the RPG elements that come from the Plasmids (abilities gained from using ADAM), which can be leveled up and new powers can be aquired the more ADAM you have. The minor puzzle parts come in the form of Hacking where you get benefits for a successful hack.
Shooting is self-explanitory, you have a gun and you shoot to kill things with them.
Plasmids are your ADAM gained, EVE powered powers, these can help you in combat when used strategically and some even have non-combat uses.
Hacking will lower the cost of vital items or give you access to caches of valuables.
The enemies you fight in the game are the spliced citizens of Rapture. They come in many forms and will fight in unique ways. Some only shoot at you, some with only melee weapons, others that will only use plasmids, and even ones that are hidiously deformed (more-so then the others) and attack like spiders.
The challange comes with the Big Daddies, they are extremely tough and some of the hardest enemies in a video game, that is, if you play on a difficulty higher then "easy" they pose a challange. When you defeat them they yield valuables and then you can get at the little sister.
Welcome to Rapture
Graphics
They are beautiful, the water looks incredibly realistic and behaves that way, and the style of the game is refreshing, especially for the sci-fi genre since it does not require space or aleins, ect.
Music
The music is strait from the 60s it seems, with maybe some exceptions, but it all fits perfectly
An excellent game and one of my favorite IPs ever.
