Art of Game Design

Games are probably the best instructional media there is -- naturally, they are mostly ignored or actively opposed by most "educators." In the years to come, we're going to need to totally redesign our system of edumacation, and recognizing the central role of games, especially when designed by the learners themselves, would be a good step toward making the change go well.

Games are not just "how-to-make-fun" -- games are the art of using a fun or absorbing activity as a way to teach skills and provide insights.

Sample excerpts:

We must be absolutely clear on this point before we can proceed. The game is not the experience. The game enables the experience, but it is not the experience. This is a hard concept for some people to grasp.

Lens #1: The Lens of Essential Experience

To use this lens, you stop thinking about your game and start thinking about the experience of the player. Ask yourself these questions:

* What experience do I want the player to have?
* What is essential to that experience?
* How can my game capture that essence?

If there is a big difference between the experience you want to create and the one you are actually creating, your game needs to change: You need to clearly state the essential experience you desire, and find as many ways as possible to instill this essence into your game.

Let's review the list of game qualities we have picked out of these various definitions:

Q1. Games are entered willfully.
Q2. Games have goals.
Q3. Games have conflict.
Q4. Games have rules.
Q5. Games can be won and lost.
Q6. Games are interactive.
Q7. Games have challenge.
Q8. Games can create their own internal value.
Q9. Games engage players.
Q10. Games are closed, formal systems.

The thing that really seems to bother people about calling puzzles games is that they are not replayable. Once you figure out the best strategy, you can solve the puzzle every time, and it is no longer fun. Games are not usually this way. Most games have enough dynamic elements that each time you play you are confronted again with a new set of problems to solve. Sometimes this is because you have an intelligent human opponent (checkers, chess, backgammon, etc.), and sometimes it is because the game is able to generate lots of different challenges for you, either through ever-advancing goals (setting a new high score record) or
through some kind of rich challenge-generation mechanism (solitaire, Rubik's Cube, Tetris, etc.)


Specifically, that the player puts their mind inside the game world, but that game world really only exists in the mind of the player? This magical situation, which is at the heart of all we care about, is made possible by the game interface, which is where player and game come together. Interface is the infinitely thin membrane that separates white/yang/player and black/yin/game. When the interface fails, the delicate flame of experience that rises from the player/game interaction is suddenly snuffed out. For this reason, it is crucial for us to understand how our game interface works, and to make it as robust, as powerful, and as invisible as we can.

Experiences without feedback are frustrating and confusing. At many crosswalks in the United States, pedestrians can push a button that will make the DON'T WALK sign change to a WALK sign so they can cross the street safely. But it can't change right away, since that would cause traffic accidents. So the poor pedestrian often has to wait up to a minute to see whether pressing the button had any effect. As a result, you see all kinds of strange button-pressing behavior: some people push the button and hold it for several seconds, others push it several times in a row, just to be safe. And the whole experience is accompanied by a sense of uncertainty -- pedestrians can often be seen nervously studying the lights and DON'T WALK sign to see if it is going to change, because they might not have pushed the button correctly.

What a delight it was to visit the United Kingdom, and find that in some areas the crosswalk buttons give immediate feedback in the form of an illuminated WAIT sign that comes on when the button has been pushed, and turns off when the WALK period has ended (Figure 13.9)! The addition of some simple feedback turned an experience where a pedestrian feels frustrated into one where they can feel confident and in control.

For all the grand dreams of interactive storytelling, there are two methods that dominate the world of game design. The first and most dominant in videogames is commonly called the "string of pearls " or sometimes the "rivers and lakes " method. It is called this because it can be visually represented like this:



The idea is that a completely non-interactive story (the string) is presented in the form of text, a slideshow, or an animated sequence and then the player is given a period of free movement and control (the pearl) with a fixed goal in mind. When
the goal is achieved, the player travels down the string via another non-interactive sequence, to the next pearl, etc. In other words, cut scene, game level, cut scene, game level...

Many people criticize this method as "not really being interactive, " but players sure do enjoy it.

If 10 choices sounds kind of short, and you want to have 20 opportunities for three choices from the beginning to the end of the story, that means you'll need to write 5,230,176,601 outcomes. These large numbers make any kind of meaningful branching storytelling impossible in our short life spans. And sadly, the main way that most interactive storytellers deal with this perplexing plethora of plotlines is to start fusing outcomes together -- something like:

Problem #3: Multiple Endings Disappoint

One thing that interactive storytellers like to fantasize about is how wonderful it is that a story can have multiple endings. After all, this means the player will be able to play again and again with a different experience every time! And like many fantasies,
the reality tends to disappoint. Many games have experimented with having multiple endings to their game story. Almost universally, the player ends up thinking two things when they encounter their first ending in one of these.

1. "Is this the real ending? "
2. "Do I have to play this whole thing again to see another ending?"

There are exceptions, of course. Star Wars: Knights of the Old Republic featured a novel type of player choice -- did they want to play the game on the "light side " or "dark side " of the force -- that is, with good or evil goals? Depending on which of the paths you choose, you have different adventures, different quests, and ultimately a different ending. It can be argued that this isn't really a case of two different endings on the same story, but two completely different stories -- so different that they are each equally valid.

Problem #4: Not Enough Verbs

The things that videogame characters spend their time doing are very different than the things that characters in movies and books spend their time doing:

Videogame Verbs: run, shoot, jump, climb, throw, cast, punch, fly
Movie Verbs: talk, ask, negotiate, convince, argue, shout, plead, complain

Videogame characters are severely limited in their ability to do anything that requires something to happen above the neck. Most of what happens in stories is communication, and at the present time, videogames just can't support that. Game
designer Chris Swain has suggested that when technology advances to the point that players can have an intelligent, spoken conversation with computer-controlled game characters, it will have an effect similar to the introduction of talking pictures.
Suddenly, a medium that was mostly considered an amusing novelty will quickly become the dominant form of cultural storytelling. Until then, however, the lack of usable verbs in videogames significantly hampers our ability to use games as a storytelling medium.

As the character tries to overcome the obstacles, interesting conflicts tend to arise, particularly when another character has a conflicting goal. This simple pattern leads to very interesting stories because it means the character has to engage in problem-solving (which we find very interesting), because conflicts lead to unpredictable results, in other words, surprises (which we find very interesting), and because the bigger the obstacle, the bigger the potential for dramatic change (which we find very interesting).

Are these ingredients just as useful when creating videogame stories? Absolutely
and maybe even more so.

One focus group I witnessed was trying to determine where the average mom drew the line about what videogames were "too violent " for their kids. Virtua Fighter was okay, said the moms, Mortal Kombat was not. The difference? Blood. It wasn't the actions that were involved in the games that bothered them (both games are mostly about kicking your opponent in the face), but rather the graphic bloodshed in Mortal Kombat that is completely absent in Virtua Fighter. They seemed to feel that without bloodshed, it was just a game -- just imaginary. But the blood made the game creepily real, and to the moms in the interviews, a game that rewarded bloodshed felt perverse and dangerous.
