Civilization doesn't have a story, it's like a board game, so it doesn't matter which version of Civ you get. Each game has a slightly different take on the overall goal: to let you forge an empire and take it to greatness in one way or another.
IIRC, one of the developers said that the way they've made Civ V, he wouldn't be surprised if there are people who play both Civ IV and Civ V side-by-side.
