Cryptonomicon

Andy Loeb's project was to figure out the energy budgets of the local Indian tribes. A human body has to expend a certain amount of energy just to keep breathing and to maintain its body temperature. This figure goes up when it gets cold or when the body in question is doing work. The only way to obtain that energy is by eating food. Some foods have a higher energy content than others. For example, trout is highly nutritious but so low in fat and carbohydrates that you can starve to death eating it three times a day. Other foods might have lots of energy, but might require so much work to obtain and prepare that eating them would be a losing proposition, BTU-wise. Andy Loeb was trying to figure out what foods had historically been eaten by certain Northwest Indian tribes, how much energy they expended to get these foods and how much they obtained by eating them. He wanted to do this calculation for coastal Indians like the Salish (who had easy access to seafood) and for inland ones like the Cayuse (who didn't) as part of an extremely convoluted plan to prove some sort of point about the relative standards of living of these tribes and how this affected their cultural development (coastal tribes made lots of fantastically detailed art and inland ones occasionally scratched stick figures on rocks).

To Andrew Loeb it was an exercise in meta-historical scholarship. To Randy Waterhouse, it sounded like the beginnings of a pretty cool game. Strangle a muskrat and you get 136 Energy Points. Lose the muskrat and your core temp drops another degree.

Andy was nothing if not methodical and so he had simply looked up every book that had ever been written on such topics, and every book mentioned in those books' bibliographies, yea, even unto four or five generations; checked out all of them that were available locally; and ordered the rest from ILL. All of the latter passed across Randy's desk. Randy read some and skimmed all. He got to learn about how much blubber the Arctic explorers had to eat in order to keep from starving to death. He perused detailed specifications for Army C-rations. After a while, he actually began sneaking into the photocopy room and making copies of key data.

In order to run a realistic fantasy role-playing game, you had to keep track of how much food the imaginary characters were getting and how much trouble was involved in getting it. Characters passing across the Gobi desert in November of the year 5000 B.C. would have to spend more time worrying about food than, say, ones who were traveling across central Illinois in 1950.

Randy was hardly the first game designer to notice this. There were a few incredibly stupid games in which you didn't have to think about food, but Randy and his friends disdained them. In all of the games that he participated in, or that he himself designed, you had to devote a realistic amount of effort to getting food for your character. But it was not easy to determine what was realistic. Like most designers, Randy got over the problem by slapping together a few rudimentary equations that he basically just pulled out of thin air. But in the books, articles, and dissertations that Andrew Loeb was borrowing through ILL, he found exactly the raw data that a mathematically inclined person would need to come up with a sophisticated rules system based on scientific fact.

Simulating all of the physical processes going on in each character's body was out of the question, especially in a game where you might be dealing with armies of a hundred thousand men. Even a crude simulation, tracking only a few variables and using simple equations, would involve a nightmarish amount of paperwork if you did it all by hand. But all of this was happening in the mid-1980s, when personal computers had become cheap and ubiquitous. A computer could automatically track a large database and tell you whether each character was well-fed or starving. There was no reason not to do it on a computer.

Unless, like Randy Waterhouse, you had such a shitty job that you couldn't afford a computer.

Of course, there's a way to dodge any problem. The university had lots of computers. If Randy could get an account on one of them, he could write his program there and run it for free.

Unfortunately, accounts were only available to students or faculty members, and Randy was neither.

Fortunately, he started dating a grad student named Charlene at just about this time.
