Marketing

Games are big business. According to the Entertainment Software Association, a blockbuster game like Grand Theft Auto: Vice City can cost between million – million to develop, with an addition million for promotion and marketing.

With so much money at stake, the publishers go to great lengths to hype their games. This begins early, often while the game is still being designed. Companies send their designers and public relations staff to trade shows and conventions all over the world to promote their latest games. Demonstration versions, or "demos," are sometimes made available for download from the Internet to offer a sneak peak, and theatrical trailers like those created for Hollywood movies are released. All of this is done so that buyers will be willing to spend to (or more) to be immersed in the imaginary world that that game designers worked so hard to bring to life.

Postproduction

Postproduction

Once the game is complete, it enters the postproduction phase. This phase includes extensive testing, review, marketing and finally, distribution.

Testing

The job of the testers is to play the game repeatedly to find all the mistakes, or "bugs." Problems are prioritized in many ways, from "fatal" bugs which must be resolved immediately, to minor issues which may or may not affect the game's release. When a problem is discovered, a detailed report is sent back to the developers and the error is corrected.

The first version sent to testers is called the "alpha" version, and it is tested to detect any major flaws in the game while they are still relatively easy to fix. Once all of the major flaws are addressed, a "beta" version is released, often to a larger group of testers that sometimes includes the public. The beta version is exhaustively tested, fixed and re-released until the developers are satisfied that the game is ready for primetime.

Usually during this testing phase, a copy of the game is sent to the Entertainment Software Rating Board to be given a rating. These ratingsare intended to give consumers an idea of the content of the game and its appropriateness for different age groups.

Code

Code

Unseen to the user, but making all of the game elements work together, is the code. Code is the set of computer language instructions that controls every aspect of the game. Most games are written with custom code based on the C programming language. A 3-D code engine is almost always used to generate the incredibly complex code necessary for all of the polygons, shadows and textures the user sees on the screen.

Another important aspect of the code is the artificial intelligence component. This is the logic of the game, and it also establishes the physics of the game world, detecting the interactions and collisions between objects and controlling their movement.

The Game World

One of the most important aspects of modern game creation is the environment. Subtle touches like reflections in shiny surfaces and varied cloud patterns often go unnoticed by players, but they help create a much more immersive environment. And often such details can propel the story forward: for example, a twig snapping under a character's foot can signal approaching danger.

As the power of home computers rapidly increases, game developers are able to create ever more realistic and complex environments. Levels of detail that were unimaginable only a few years ago are now commonplace. It's hard to imagine the game worlds that await us in the future.

The majority of 3-D objects created for computer games are made up of polygons. A polygon is an area defined by lines. Each polygon has a set of vertices to define its shape, and it needs information that tells it what to look like. The most commonly used method to transmit this information is "texture mapping."

You can think of texture mapping much like wrapping a present. Each side of the box being wrapped is a blank polygon and the "paper" is an image of the texture to be applied. Most video game consoles and computers contain a special chip and dedicated memory that store the special images used for texture mapping and apply them to each polygon on the fly. This allows games to have incredibly detailed 3-D environments that you can interact with in real time.
