Center control is an important aspect of playing chess, most openings are built around controlling the center, but why? Is center control really that important for winning a game?
The center is the crossroads of the board. Controlling it will give you access to every other part of the board. At the same time, it will drive a wedge in the opponent's position that hampers communication between king and queen side.
Control of the center is usually a decisive advantage in your favor; unless your opponent has heavy compensation (e.g. more than a pawn of material advantage), or a violent attack against your king.
2One thing I would like to add to this for clarification is that there are two methods of center control: direct and indirect. Direct control involves occupation of the center and is the characteristic of the romantic/classical school. Indirect control involves putting pressure on the center and controlling central squares without occupying them. This is the mark of the hypermodern school.– DennisJan 5, 2013 at 8:06
The piece in the center four square can move to more positions than in it is in any other positions on the board. So if you can get control of the center positions, you have more options and this gives us an advantage over the opponent.
Controlling the center allows you to move your pieces to the other side of the board easier.
Further, some pieces (especially knights) have more moves if they're in the center of the board. A knight in the center has 8 moves. A knight on the rim has 4, 3, or 2.

First of all, EVERY reasonable chess opening is focused on the center in the first few moves. Even hypermodern are focused on the center even if they don't play for it directly.
Why is it important?
White has the first move advantage and there are a finite number of squares on the board. If white can turn his first move advantage into controlling more squares than the opponent then white can have a sustainable advantage. Otherwise, white's advantage will dissipate into nothing as the game goes on.
You could say why doesn't white grab space on the wing? The reason is that the opponent can grab more on the other side. If you play 1.g4 and I respond with 1...d5 I'm at least equal because I control more of the board.
Another way to look at it is this. Whenever you put a game into an engine it gives you a score. That score is based on the value of the pieces. The value of the pieces is based on their mobility and their mobility is based on control of space specifically in the center.
