The story carries the single player in many ways. One problem with stories they always seem to sound the same and the ending also sounds the same. Some video games that have a great story is Fallout, Mass Effect, Dragon Age, Gears of Wars, and games from Rockstar's games are some example of good games or series. For most shooter the story is about some kind of revenge and for RPG they are mostly about having to save something or for revenge.

The start of the game you will start at a character creator or they will give you a charter you would normally have to go thought some kind of tutorial from shooting at some kind of shooting rang or running from a dragon or they will put you in a mission that will teach you the basics of the game.
