Why I Left Fallout 2

1. The Crash Bug That Almost Killed Fallout 1

Before Fallout 1 could ship in September 1997, the team discovered a devastating random crash bug. It was the worst kind — completely non-deterministic. Some people crashed after minutes, others could play for hours. Every crash report pointed to different locations in the code, revealing a memory overwrite bug: some code was randomly writing junk into memory, causing the game to fail in unique ways each time.

Tim assigned contractor Mark Harrison to investigate. Mark invented what he called a "bear trap" — he'd write formatted data into memory locations, then check later if anything had corrupted them. By moving the traps closer and closer together, they could narrow down the offending code. Tim joined Mark for 5-6 hours each night after his regular 8-hour day, working 14-hour days for the final two weeks before ship.

During this time, Brian Fargo would show up in Tim's office and scream at him. Tim tried to reason that nobody wants to ship a randomly crashing game, but the pressure was relentless.

After two weeks, late one night, the bear traps had closed in on a single function call. The bug was trivially simple: a for-loop using <= instead of <, occasionally writing one element past the end of an array. Because the game was recompiled daily, what that overwrite corrupted changed with every build, making it appear random. It wasn't Tim's bug, and it wasn't Mark's. A trivial fix, sent to QA, verified, and shipped.

2. The Sequel Nobody Asked For

Tim had never planned a Fallout sequel. There were no story hooks, no system mechanics designed for extension — they hadn't even planned what would happen past level 20. The only times a sequel came up during Fallout 1 development were:

• The naming meeting, where Tim argued against "Vault 13" because it wouldn't make good sequel titles
• The manual's blank page, where lead artist Leonard Boyarsky created the Garden of Eden Creation Kit (GECK) ad as filler for an empty last page — a throwaway joke that became a major Fallout 2 plot device

A few months before Fallout 1 shipped, a separate team under Fred Hatcher had already started Fallout 2, with designers Matt Norton and Dave Hendee. Tim's team was focused on finishing Fallout 1 and then working on patches.

3. Fargo's Forced Takeover

After Fallout 1 shipped to great reviews and talk of "revitalizing the RPG genre," Brian Fargo rejected the Fallout 2 team's design pitch and came to Tim demanding he write one instead. Tim didn't want to work on Fallout 2 — he wanted to do something new.

Leonard Boyarsky and Jason Anderson had their own pitch ready: a giant war machine — a rolling monstrosity destroying everything around the world, because "war never changes." Brian liked it but said he didn't see Tim's hand in it. He insisted Tim be involved.

The three of them wrote a new pitch together. The early areas — Arroyo, Klamath, The Den, Modoc — closely matched what shipped. But the later game diverged significantly after Tim left:

• The Enclave was very different in the original pitch — no president in power armor
• There was supposed to be a spaceship being built
• The humor changed dramatically (more on this below)

Brian loved the pitch, then told Tim to just run the whole project. Tim discovered that Fred Hatcher's promised producer promotion had never materialized. He took over around November 1997.

4. The Humor Problem

Tim considered himself the tonal guardian of Fallout's humor. His rule: if someone doesn't get a joke because it requires specific cultural knowledge, they shouldn't even know a joke was made — or there should be another layer that's funny regardless.

When Tim left, this philosophy "went out the door." Fallout 2 became filled with in-your-face pop culture references where players who didn't recognize the source would clearly see they were missing something. There was fourth-wall breaking (the "den of bad memories" area). Tim had occasionally broken the fourth wall in Fallout 1, but pushed those moments into random encounters gated by the Luck stat — keeping them subtle and optional.

5. Corporate Interference

Once Fallout was a hit, everyone wanted in. People Tim had never spoken to started claiming credit. At a marketing meeting, a woman he'd never met announced that an external company was already doing Fallout 2's box cover — even though Leonard's team had created the original box art in-house (which was far better than any professionally commissioned alternative).

Tim ran into Fargo in the hallway afterward and told him decisions were being made about Fallout 2 without his knowledge or input. Fargo offered to fire the woman. Tim said no — he just wanted to be involved. He asked to go back to how Fallout 1 was made: let the team work in peace, since they'd already proven they could deliver.

It didn't matter.

The Temple of Trials — widely considered one of Fallout 2's weakest elements — was mandated from above. Tim was told there had to be a tutorial. He asked if players could skip it. No. What about on subsequent playthroughs? No.

6. The Bonus Incident

This was the breaking point Tim had never publicly discussed before this video.

After Fallout 1 shipped, Fergus (Tim's boss) gave him a pool of bonus money to distribute to the team. Tim created a transparent spreadsheet with three factors:

1. Base salary (objective)
2. Months on the project (objective)
3. Unique contribution (subjective, but kept as a small modifier)

For the subjective factor, Tim asked one question per person: "If this person hadn't been on the team, would it have been substantially worse?" He highlighted people like Scott Everts (map/technical artist who mastered the world map editor — a "quiet powerhouse") and Leonard Boyarsky (whose idea of "what the 1950s thought the future would look like" informed everything people love about Fallout). He also lowered the number for someone who hadn't finished a huge chunk of their work, requiring others to step in.

Tim and Fergus signed off. HR received the spreadsheet. That was the last time either of them saw it in its original form.

6.1. What Fargo Did

When Tim received his own bonus, it was in the bottom third — despite being project leader, producer, lead programmer, designer, and the only person on the team from the very beginning.

Tim went to HR. "No mistake." He pressed. Finally: "Fargo did this."

Tim confronted Brian, who explained two changes:

1. He disagreed with Tim reducing one person's bonus, so he gave that person part of Tim's bonus
2. The big one: Fargo had demanded to know whose bug caused the ship delay (the crash bug). Tim refused to name the programmer, saying it wasn't malicious and he was the project lead — it was his responsibility. Fargo's response: "You wanted responsibility for it, so take it" — and slashed Tim's bonus accordingly.

Tim asked if this was supposed to motivate him to work on Fallout 2. Fargo said: "I encourage you to do better next time."

7. The Resignation

Tim went home and drafted his resignation. He sat on it for two weeks.

One morning he told Leonard and Jason he was quitting, then gave Fergus the letter with three options: leave that day, two weeks' notice, or end of the month. Fergus chose end of the month.

The executive producer told Tim "people are going to be pissed." Tim didn't care — he was done.

When he returned to his office two hours later, Leonard Boyarsky and Jason Anderson had copied his letter and resigned as well.

Nobody was happy — not the team, not Brian, not Fergus. But Tim couldn't stay. As he summarized it:

He made an IP from scratch that he'd always believed in, that nobody outside the team had believed in until near the end. His reward was more crunch, more unwanted responsibility, interference from people who'd ignored them for three years, and a reduced bonus meant to "motivate" him.

8. Tim's Closing Note

Tim explicitly asked viewers not to change their opinion of Fallout 2 because of his story. If you like Fallout 2, enjoy it — a really good group of people worked on it. He just couldn't do it anymore. "That's sometimes how development goes."
