How can I be so up on screenplay story structure, and so blind when it comes to my own game?
A story doesn’t move forward until a character wants something. So – a game doesn’t move forward until the player wants something. Five seconds after you press start, you’d better know the answer to the question: “What do I want to happen?”
There always has to be a range of possible outcomes, some better than others, so you’re constantly thinking: “Good… Bad… Terrible.” Every event has to move you closer or further away from your goal, or it’s not an event, it’s just window dressing.
The overall goal of POP is to get the girl. But that’s not a strong enough magnet to pull the player through all that distance. It needs sub-goals.
Beating a guard in Karateka buys you time to gain distance. You want to get closer to the palace because the princess is there; every guard you beat brings you closer. It’s simple, but it works. In psychological terms, it even follows the classic addictive pattern of diminishing rewards: each subsequent guard is harder to kill, and gives you a smaller reward for your pains, until you reach the intermediate goal (the end of the level), at which point there’s a bigger reward, and things get easier again…. for a while.
Getting through a dungeon in Prince of Persia doesn’t give that satisfying feeling of getting closer to the goal. Partly because it all looks pretty much the same. That, I can fix.
But there’s another key element in story stucture that also applies to games, and is missing from this one: The Opponent. Someone competing for the same goal as the hero, or trying to stop him from attaining it. The more human, the better. (The days of Asteroids and Pinball are over.)
In this case (we’re short on time, so let’s use the opponent we’ve already got), it’s Shadow Man.
Some games boast a whole series of different opponents. (According to Truby, this is characteristic of Myth, and it weakens the story.) We’ll make the shadow man your opponent for the entire game. You’re competing for hit points. Each blow you deal him weakens him. Each power dot you eat makes you stronger. But if he gets there first and he eats it, he gets stronger. So when you face each other with crossed swords, the balance of power is not predetermined (as in Karateka), but is the result of your own actions thus far in the game.
It links the combat with the running-around. It’s brilliant. I love it!
(Forget the boring damn keys.)

Spent the morning talking to Eric about the game. Conclusion: My next step should be to implement the fighting. Until I do, it’s too difficult to imagine in the abstract what the game will feel like to play.

Showed POP to the Tribunal – Gary, Gene, Brian, Sophie K. (of Marketing), and Ann Kronen.
Ann and Sophie, who hadn’t seen it before, gasped over the animation. Gene grudgingly admitted it might be pretty good, “if it ever becomes a game.” Gary liked the puzzle angle, didn’t mind the two disks, liked the level editor, didn’t think it needed all that much combat, thought it had big conversion and coin-op potential and I shouldn’t limit it on account of the Apple II’s shortcomings.
I’ve got to learn to get more pumped up for these things. I was so blasé, I really brought the energy down in the room. I think they’d have been more excited if I hadn’t been there to demo it.

A glorious day. Freezing cold, but maybe that was part of it. The air was so clean, the sky so blue; I felt happy for no reason at all. I drove 80 on the freeway blasting Talking Heads all the way home.
Today definitely marked the close of a week of anguish over my game. It’s gonna be great. I put in a set of chomping jaws that added some much-needed real-time danger to the action. That was easy. The big step will be the swordfighting with the guards, but it’ll be worth it.
If only the Apple II weren’t a dying format. Better get cracking pronto on the MS-DOS conversion.
October royalty check for Karateka was $166.

Worked all day again, made great strides. I put in a strength meter and made it work. I also put in footsteps, and improved the chomping jaws.
But the real breakthrough this week was invisible: I moved a bunch of stuff around so the main game code can use the auxiliary language card. Basically, I’ve just freed up an extra 12K. That gives me some breathing room I’ll sorely need if I’m going to put in all this swordfighting.
It was a good weekend.

Put in burning torches, and bricks in the background. It’s totally changed the look of the game. Robert was impressed.
I’m very happy with how things are going. With combat, this will be one of the greatest games of all time.
