I got a request via Twitter for this old essay which had fallen off the Internet, so I am posting it here. Thiswas originally written for Metaplace users… there is nothing here new to anyone who has followed the blogfor a while, but since it was requested, here it is.
The fundamentals of game design
Starting out creating an interactive experience, of any sort really, can be rather daunting. In this tutorial, we’llrun through the basic components of a game, so we can get a handle on what the next steps are when youmake the jump from the training tutorials to your own projects.
Often people have trouble when conceptualizing a game. The idea, after all, is often the easy part. It’sactually making it, and figuring out where to start, that is the hard part.
A friendly warning, though! Just like writers have different ways of working, and some composers writemusic in their head and others at an instrument, different game designers are going to have different ways ofworking. Some work better “in the code” and others like doing everything on paper beforehand. Some thinkin terms of story and narrative, and others are systems designers first and foremost. So this tutorial mayactually run a bit against the grain for you, depending on your natural temperament.
In what follows, I am going to use the language of games, but really, every piece of advice in this articleapplies equally if you are designing any sort of interactive project whatsoever. So just because I say “game”in what follows doesn’t mean this article won’t be useful to you when you start making a classroomexperience or a chat room or some other application.
The components of a game
The first thing to understand is that games are made out of games. A large game is actually composed ofminigames. Even a small game is built out of very very simple small games. The smallest games are ones thatare so simple and stupid, you can’t lose. You can think of this as “game atoms,” if you like.
For example, in the classic puzzle game Tetris, the basic game is beating your high score. To beat that game,you have to master the game of forming lines. There’s actually multiple variants there, because you have to

learn the games of placing all the different sorts of blocks. And finally, the simplest game is rotating a block,which is just a button and hard to screw up.
So games are built out of games. This brings us to key piece of advice #1:
Advice #1: Design one game at a time.
Turtles all the way down
Even if you are making a complex game, built out of many “game atoms,” each atom is a game in its ownright, and has to feel fun and satisfying. Even the stupid ones with no challenge have to feel good. Imaginehow poor a game Tetris would be if the stupidly trivial game of “press a button and watch the block spin”wasn’t satisfying.
Many games are ruined at this very fundamental level by poor design. For example, a bad designer mighthave decided that a random chance of the block not rotating would make sense. After all, we use randomchance in gambling, board games, and roleplaying games, right? But it would make Tetris unplayable.
Game atoms
OK, so you’re going to design one of the game atoms. Luckily, every game atom has the same characteristics:
A player does something.The opponent (which might be the computer) calculates a responseThe player gets feedback.The player learns from this feedback, and gets to do something again.
You can think of these steps in very abstract terms:
InputModelFeedbackMastery
Really, that is it. Let’s apply it to our Tetris example again. At the trivial “rotate a block” level, we have
A player hits a button.The computer calculates that this means rotate the L counter-clockwise.The player is given the feedback of the block in its new position.The player figures out “I bet I can do this with other sorts of blocks too. And there’s probably a rotateclockwise button somewhere. Rotating is my goal!”
Advice #2: make sure the controls match up well to what the player is attempting to do.
At a more advanced level we have
A player can rotate left, right, drop a block, glance at the next block, etc. Lots of choices.The computer is going to take its turn and move the block further down regardless, or spawn a newblock of a random shape if there isn’t one.The block moves down. Maybe it completes a line, maybe it doesn’t.The player says “aha! Completing lines is my goal, and different shapes help or hinder that!”
Notice that if any of these four steps is poorly chosen, the whole game sucks.

A player moves the mouse.The computer figures this means rotate a block.The player is not shown the block, but instead a stock quote.The player is baffled and quits.
Advice #3: make sure the player can actually learn from the feedback you give them.
Where does the fun come from?
The fun comes from the mastery process. But what the player is mastering is the model. All games aremathematical models of something. We often speak, for example, of Chess being like war (we actually speakof lots of games as being like war!).
Even games like Tic-Tac-Toe are expressible as math puzzles. Games of resource management over time (likean RTS or Civilization) are exercises in calculus. RPGs where you make choices in character building areactually examples of exploring possibility spaces searching for local maxima… games lie to us all the timeabout what they are really about.
Advice #4: try to stop thinking about what your game looks like, for a moment, and think about what it isactually modeling.
The underlying math
All this sounds incredibly geeky, but you don’t have to be a math geek to enjoy games. The trick is to makethe pill go down easy. And the fact is that some math problems and models are more interesting than others.Nobody is that interested in a game that pushes you to solve “2×5 = ?” over and over. It has to be a sort ofproblem that you can come to again and again, and explore possibilities looking for alternate solutions andpaths.
This means that there’s a specific and highly varied set of problems that make for good games. In math, a lotof these problems are what is called NP-Hard problems. You don’t need to dig into higher mathematics to bea good game designer, though. Instead, you need to ask yourself a basic set of questions:
Where?When?How?What?With?For?Few?Phooey.
This list seems facetious, but it’s a shorthand way of asking yourself the following questions about your gameatom:
Do you have to prepare for the challenge?
…where prep includes prior moves? …and you can prep in multiple ways?
Does the topology of the space matter?
…does the topology change?

Is there a core verb for the challenge?
…can it be modified by content?
Can you use different abilities on it?
…will you have to in order to succeed?
Is there skill to using the ability?
…or is this a basic UI action?
Are there multiple success states?
…with no bottomfeeding? …and a cost to failure?
You have to answer yes to all of these for your game atom to be fun. And yes, we mean every atom in thegame has to meet these criteria.
Advice #5: check this list for every goal, every objective, every button press, every action a user can take,every decision they make.
How do you get there?
There’s really only one way, right now. You prototype and iterate. Don’t get hung up on the visuals, exceptfor worrying about whether you are giving enough feedback. The best games can be played using sticks andstones. (You can play most roleplaying games with pretty much any random chance generator, for example).
You can prototype with all sorts of things. I have a “prototype kit” because I often prototype using physicalobjects before going into the code. It consists mostly of stuff that I can pick up at a craft store:
Two decks of regular cards.One deck of Uno cards.One Go board.One Checkers board.A half dozen six-sided dice.One full set of polyhedral dice.A large stack of differently colored index cards.Twelve pounds of differently colored beads. Go to the pottery aisle at your local craft store — these arethe kind that get put in fish tanks and potted plants. It’s a bit more than a buck for a pound of one color.Wooden pieces, also from the craft store. These are found in the aisle with the clock faces:
wood cubes, various sizescolored flat squares, three sizesdowel rods‘pawn’ pieceswooden chip (circles)assorted circles, hexagons, stars, etc
Blank wooden clock faces that you can draw boards on.Wood glueDremel toolSquare glass chips (also from the craft store, asst colors)
But even that is overkill for most people.

Advice #6: watch others play your game – you’ll quickly see where you didn’t provide enough feedback, orwhere they can’t figure out the underlying model.
A final thought
Fundamentally, never forget that if you want to design, you have to just go do it. The only way to get better atit is to keep doing it, because gamemaking is in itself a great and varied game to play.

I love it when you post game design essays, Raph!
I’d like to hear about the design of SWG like you did with UO.Heck I’d like to hear more about the design of UO!

Slightly to the left of the topic but if you want to apply some of what Raph describes here:

Your creations have all been such stunning successes.

Actually, from a business sense, they all have, in the end. Some of them dramatically so.
And in terms of game design… enh, I’ll let others decide that. For me it’s enough to know thatmillions of people had fun. *shrug*
