The Intensity Table

Between the empty white box and the built level there is an artifact almost nobody writes about: a table in which every planned event gets a gut-voted number from one to ten, and a set of rules about how the numbers are allowed to move. Four primary texts from 2008 to 2013 — a production plan, an operational definition, a warning, and a practice report — describe the same curve at four different scales. All four were re-fetched live and text-verified on the day of publication, and every live URL carries an archive double.

This essay sits in a gap the previous reports in this series left open. Pull Toward the Blockage was about the design of one space — Barlet's whitebox, Montazeri's twelve steps, the blockout as the unit of thought. The Interconnected Landmass was about the meaning of the whole world. Neither one talks about the arithmetic between them: how a campaign of thirty levels gets ordered at all, before a single one is blocked out. The corpus answers that question with a spreadsheet, and the answer is older and more numerical than the craft literature usually admits.

Lopez: the plan that exists so you stop throwing away levels

Mike Lopez, a former EA and THQ design director writing for Gamasutra in November 2008, opens his nine-step feature with an accusation: that studios still design levels ad hoc, and pay for it in deleted work. The opener of his series, and the trigger for the whole method, is the observation that the industry keeps repeating the same expensive mistake:

Many game developers in this day and age still utilize a very old-school, haphazard on-the-fly method of level design. When questioned, they argue they can produce a quality campaign with this technique. The reality, however, is that the cost of continually reworking levels and missions until a user-appealing structure is realized is extremely prohibitive.

His exhibit is BioShock — and here the honesty clause of this essay begins, because Lopez himself flags the claim as hearsay about a studio he did not work on: "I believe all of the missions were entirely redone in the final nine months, and I suspect much of the level layout and content was redone as well." That is an "I believe" doing the work of a source, and it has been preserved as exactly that. What the claim was supposed to prove — that late rework at scale is real and ruinous — is not in dispute; the number and the scope are his memory, not a postmortem.

The counter-move is a pre-production document Lopez calls the Intensity & Pacing Plan: a structured level plan "with set intensity magnitude and trend targets for the events in each level and over the entire campaign." Its engine is a table. The team brainstorms locations and action events, then ranks them by voting on intensity — "just vote on which concepts seem more intense and rate them on a relative scale of say 1-10" — and the votes become columns. From the table, four rules fall out, and they are the closest thing in this corpus to a published standard:

Two things deserve to be said about the table's honesty, and Lopez says both of them himself. The 1-10 number is explicitly a group gut feeling — "perceived gut-feeling intensity values voted by the group" — not a measurement; the method's claim is not that the number is true but that writing it down and trending it beats not having it. And the plan is allowed to fail on schedule: step eight contains a kill-switch, that if the project is "more than two thirds of the way into production without completing the initial implementation of all levels/missions, then a full round of level/mission cuts should occur immediately," with the cuts sized 30-50% beyond what the schedule predicts. A planning document whose final clause is "cut yourself smaller" has at least thought about its own failure mode.

One paragraph later the same discipline almost contradicts itself: Lopez reassures the reader that "you need not make your projected ratings perfectly hit all the projected intensity targets on paper. Just get as close as possible, and ensure that the appropriate increasing trends are upheld." The numbers are a trend instrument, not a scoreboard — the only thing that has to be strictly monotone is the trend.

Hoffstetter: the same curve, one octave down

Five years later, in February 2013, Travis Hoffstetter published a Featured Blog post that supplies the definition Lopez's table was missing. Where Lopez borrows "intensity" as a shared vocabulary word, Hoffstetter operationalizes it:

At any point in a combat encounter, a player may assess the situation, attack their enemies and/or move. The more times the player stops what they are doing to pick a new action in the combat plan, the more intense the encounter becomes.

Intensity is a re-planning frequency. Pacing is then defined on top of it — "we need a mathematical definition for pacing, intensity over time" — and the encounter pattern Lopez applies to a whole campaign reappears at the scale of a single firefight: "introduce the enemies, initiate the combat, escalate the combat, allow a midpoint for a breather and then end in a challenging climax." The midpoint breather is the same trough as Lopez's scenic reveal, one octave down. Hoffstetter even names the split the table implies: "Pacing is the science and sequencing is the art" — the curve is the plan, the enemy types and spawn timings that trace it are the craft.

Two honesty markers here, one of them about the middle of a quotation. The pattern is attributed to a "respected God of War designer, Mike Birkhead," in his blog Flark Design: "Great fights have a flow to them. They start off strong, sure, but they also build; eventually building to a final crescendo." That sentence survives only inside Hoffstetter's retelling — the Flark Design blog's domain no longer resolves, and the Wayback Machine's snapshots of it predate the article in question, so the Birkhead original is unprovable; it is quoted here because Hoffstetter quotes it, and flagged as a chain of length two. Second, the same post asserts a reading-direction eye-scanning routine ("Most people read from left to right and that causes the human eye to start in the left upper corner") as a "fun fact" with no source attached, and uses it to order enemy spawns. That claim is folklore dressed as science, and unlike the rest of the post it is not backed by his playtest procedure. The post's own method — "The intensity and time numbers used to plot pacing graphs need to be driven from play tester results... watch their crosshairs" — is genuinely empirical for a designer's kitchen-table standard, but the zero-to-ten scale underneath it is the same unvalidated number as Lopez's, and Hoffstetter's 0-10 is his own construction, not an instrument.

What matters for the series: Hoffstetter's definition retroactively explains what Lopez's spreadsheet was counting. A campaign ordered by voted 1-10 numbers is ordering re-planning pressure across thirty hours; a fight ordered by watched crosshairs is ordering the same pressure across ninety seconds. It is one variable, measured at two scales by two different rituals — a conference-room vote in 2008, a playtester's crosshair in 2013.

Serviss: the number that cannot buy you a landmark

If the table is the thesis and the definition is the antithesis-ready upgrade, Ben Serviss's June 2013 Featured Blog is the counter-argument against the one thing a pacing plan cannot budget for: borrowed emotion. Writing about levels that re-create real landmarks to make the player feel something, he quotes a fellow developer, Andrew Grapsas: "You can get some emotional resonance from a real-life location, but that requires the location to already resonate." Then he delivers the sentence that should be embroidered on every level with a real-world set piece:

Because the nature of gameplay demands that players evaluate their surroundings through a functional lens, the opportunity for emotional resonance is diluted as even the most elegant architecture is parsed into simple geometry. The columns of the Parthenon become overlarge cover; the concourse at Grand Central Terminal becomes the sniper zone.

This is the direct opposite pole of the beckoning-hand tradition this series traced earlier: the landmark that is supposed to pull the player in gets reduced to ballistics the moment the player starts playing. Serviss's alternative is the generically relatable space — again quoting Grapsas: "That's why semi-generic spaces work well, like an airplane. We can all relate to being on an airplane." His counter-example is telling: Grand Theft Auto's adapted cities work, in his reading, because the decision "pervades the entire game" — the place is a system, not a level. The pattern matches Lopez's frame from the other side: a borrowed feeling scheduled into two levels of an otherwise-generic campaign is a trough the pacing table cannot fill, because the table can allocate intensity but not resonance.

Serviss is also the least hedged writer of the four — an opinion piece against a fashion, with no playtest behind it, and his Grapsas/Seifert conversation is an internal source (the two are colleagues of the author). This essay keeps the Parthenon sentence because it names a mechanism the other three never touch, not because it was measured.

Sleeping Dogs: the table, but with a map

The practice voice in the set is older than the theory: in June 2012, United Front Games told Gamasutra how it was pacing Sleeping Dogs, and the executive producer's summary could open any lecture on Lopez's plan: "Controlling the pacing is probably one of the most difficult things to do." The production answer was structural — keep the story linear inside the open world so each session "picks up from where you've left off," then do the table's ordering work in map space instead of level space. Senior producer Jeff O'Connell's account is the closest thing to a field report the corpus has:

While we do have a linear narrative, we've really taken a lot of our core start and end points of our scripted missions and analyzed those areas and the routes that we think that players will take and finely crafted a lot of our secondary and ambient encounters around those. We've actually even made our own version of Google Maps where we look at all of the content in the game, and by using this program we can actually go in and really scrutinize the different routes and play-styles that players will use.

Read that against Lopez's trough rule. His lulls are authored inside a corridor; Sleeping Dogs builds the lull budget out of ambient encounters placed along predicted player routes — the valley between peaks becomes a map-painting exercise. This is also the production practice underneath the interconnected landmass this series described earlier: the player's mental map gains meaning from where content sits relative to where players actually walk, and here a studio built a private mapping tool to find out where that is. One flag: the piece carries no author byline (a 2012 Gamasutra staff item), and the makers being quoted were promoting a game two months from release — it is interview material, priced accordingly.

What the table is for

Stack the four and an odd shape appears. The blockout — the unit of the previous essays — is the last step of this process, not the first. In 2008, Lopez tells level teams to sequence voted numbers before any geometry exists; in 2013, Hoffstetter tells them the numbers are re-planning pressure and the test is a watched crosshair; in 2012, Sleeping Dogs tells them the same ordering happens over a city, one route at a time; and Serviss stands off to the side warning that the entire exercise allocates a resource — intensity — that never converts into the adjacent-sounding one, resonance. The terror Montazeri expressed about convergent blockouts — we all design similar blockouts, and that's terrifying — has a quiet cousin in this literature: we all also schedule the same trough-peak-trough, by the same vote, against the same crescendo. The difference is that this literature knows it is a template, prints its own kill-switch, and tells you when to distrust the number.

A final note on the sources, since this series keeps its receipts: all four live pages were re-fetched and read end-to-end on the day this essay was published, and each carries an archive double returning HTTP 200 — Lopez at snapshot 20220818005345, Hoffstetter at 20240828060202, Serviss at 20250216210505, the Sleeping Dogs interview at 20210827110133. Serviss's post carries its own provenance note — it "originally appeared on dashjump.com" — which this essay preserves because link rot is the reason for the doubles in the first place.
