Before I start this, I would like to say that this game is massive, and I could not even begin to scratch the surface of its content. It has hundreds of hours of gameplay. Anyways, Skyrim is an open-world RPG game developed by Bethesda Studios. It was released November 11th, 2011, and is still actively played to this day. The game is so widely praised for its "do anything you want" sort of attitude. Everything you do in this game matters, and it matters a lot. It will change the plot line entirely, which adds an element of replay-ability. The very-very basic story is you are Dragonborn, which lets you absorb the souls of dragons that you have slain. Your goal is to kill Alduin, the world eater. He is essentially "the big kahuna" of the dragon world. He is able to literally eat worlds, as his title suggests. I promise you it is more interesting than how I just descibed it, so Ill link an extended plot down below.
The Plot Taken From Here

The player character is a prisoner being led to an Imperial execution in Helgen overseen by General Tullius, which includes Ulfric Stormcloak among the prisoners to be executed there. Alduin unexpectedly interrupts the procession, destroying the town before the player can be executed. The player escapes in the chaos and journeys to the city of Whiterun to request aid against the dragon threat. After slaying a dragon that attacks nearby, the player absorbs its soul, which grants them the ability to perform a shout. The city's amazed guards inform the player that they must be Dragonborn. The player is summoned to meet with the Greybeards, an order of monks who live in seclusion on Skyrim's tallest mountain, the Throat of the World. The Greybeards train the player in using shouts and inform the player of their role in stopping Alduin. The player learns that Skyrim's civil war is the last in a sequence of prophetic events foretold by the Elder Scrolls, which also predicted the return of Alduin.

The player later meets with members of the Blades, an order of dragon hunters. The player and the Blades travel to Sky Haven Temple to find a prophetic engravement on Alduin's Wall and learn that ancient Nords used a special shout against Alduin so they could engage him. To gain more information, the player meets the ancient dragon Paarthurnax, the leader of the Greybeards. Paarthurnax reveals that Alduin was cast into the currents of time by the use of an Elder Scroll in the hope that he would never reemerge. The player locates the Elder Scroll and uses it to peer through a window in time and learn the shout to combat Alduin. The player battles with Alduin, who then flees to Sovngarde, the Nordic afterlife, to gain strength by devouring the souls of deceased Nords.

The player summons and traps a dragon named Odahviing, and learns from him that Alduin has fled to Sovngarde through a portal located at an ancient fort called Skuldafn. Odahviing agrees to fly the player to Skuldafn, claiming Alduin has shown himself as weak and undeserving of leadership over the dragon race by fleeing from the Dragonborn. The player enters Sovngarde and travels to the Hall of Valor. There, they meet up with the three heroes of Nordic legend who defeated Alduin originally. With their help, the player defeats Alduin once and for all.
