Video Games have been around for over thirty years now. A lot have changed in the way programs work. When they first came out Video Games weren't that powerful because the hardware couldn't support it. Now the possibilities are almost endless.

Games have changed so much. From Games like Asteroids that was made in 1979.

With Asteroids being only a small program with some computations going on.

To current games like Half-life 2. With so many physics computations going on. They try to make this game the most realistic game.

Out there. The current trend in video games is to make them more and more realistic. The more realistic they make the game.

The more equations the program has to do, so the program is a lot bigger and needs a lot more power to do everything the game wants.
