10 Fascinating Details About Tim Cain's Unmade Time-Travel RPG

Tim Cain, co-creator of the legendary Fallout series, frequently shares tantalizing tales of projects that never saw the light of day. Among these glimpses into gaming's alternate timelines, one proposal stands out: Time Walker, a first-person RPG that would have let players assassinate historical figures, create paradoxes, and balance the very fabric of reality. Drafted alongside fellow veteran Jason Anderson during the Troika years, this ambitious concept remains a treasured “what-if” in RPG history. Below are ten key insights into this unrealized time-travel adventure.

1. The Vision: A First-Person Time-Travel RPG

In 2000, Tim Cain and Jason Anderson pitched Time Walker as a first-person RPG centered on time travel. The game would cast players as a “temporal agent” tasked with preserving their own timeline. While it never progressed beyond a written proposal, the scope was immense by any standard—especially considering the then-current hardware limitations. The developers envisioned a fully realized system where player actions directly impacted the stability of reality, making every decision matter.

2. The Role: Playing a Temporal Agent

Players would assume the role of a temporal agent, a guardian of their own timeline. Their mission? To ensure their reality’s existence by completing objectives across history. Enemy agents working to rewrite the timeline would complicate matters, forcing players to think tactically about where and when to intervene. The agent’s gear would evolve based on the timeline’s stability, tying progression directly to narrative consequences.

3. Reality Check: Balancing Timeline Stability

A core mechanic was the timeline stability meter. As players completed missions, stability would fluctuate. Success restored order; failure caused reality to fray. If stability dropped too low, the player’s reality would become impossible, resulting in a game-over condition where they simply “cease to exist.” This high-stakes loop demanded careful decision-making, as each action had the potential to erase the player from existence.

4. Gear Progression: From Standard to Fantastic

Instead of a standard loot curve, Time Walker inverted the formula. As the timeline grew unstable, players would gain access to anachronistic technology—gear that became more fantastical and improbable. A stable timeline meant a conventional arsenal; an unraveling one unlocked future-tech weaponry and gadgets. This created a risk-reward dynamic: embrace chaos to wield powerful items, or restore order to survive with simpler tools.

5. Mission Examples: Killing Pharaohs and Creating Paradoxes

Cain shared three sample missions that highlight the game’s creative freedom. One involved assassinating a pharaoh in ancient Egypt. Another required giving a young girl a specific doll on her eighth birthday—a subtle butterfly-effect task. The most audacious mission was to create a paradox by preventing the invention of time travel itself. These examples show how the game would blend murder, manipulation, and logical loops.

6. Inverted Difficulty Curve: Easier as Time Unravels

Most RPGs get easier as players level up and gather better items. Time Walker flipped this: the game would become easier as the timeline destabilized (thanks to anachronistic gear) and harder as order was restored. This unconventional curve meant players had to strategically choose when to exploit chaos and when to push for stability. It was a bold design choice that would have changed how players approached every encounter.

7. Historical Figures and Locations

The pitch boasted 15 different time periods, each featuring real historical figures. Players could meet and interact with (or assassinate) everyone from Egyptian pharaohs to future inventors. The variety of settings—ancient, medieval, futuristic—would have required massive asset creation, but Cain and Anderson believed the diversity would keep the gameplay fresh and unpredictable.

8. Platform and Multiplayer Plans

Remarkably for its time, Time Walker was designed with console and online multiplayer in mind. The team targeted the original Xbox and planned to include networked play. This was ambitious for an RPG in the early 2000s, especially one focused on time travel. Multiplayer could have allowed players to experience the timeline chaos together, though details on how exactly it would work remain sparse.

9. Skill Tree and Open-Ended Solutions

Drawing from the team’s CRPG roots (like the original Fallout), Time Walker featured an open-ended skill tree that enabled multiple solutions per mission. Whether through stealth, combat, or dialogue, players could approach each time-jump problem creatively. This non-linear design echoed the branching paths of classic isometric RPGs, but translated into a first-person perspective with real-time action.

10. Legacy: Connection to Clockwork Revolution

Though Time Walker never materialized, its ideas live on. Jason Anderson is now principal designer at InXile on Clockwork Revolution, a first-person time-travel RPG that explores similar themes of reality manipulation. Cain’s YouTube channel continues to share such prototypes, reminding us that even failed pitches can influence the games we play decades later. Time Walker remains a fascinating “what-if” that shaped RPG design thinking.

In the end, Time Walker stands as a testament to the boundless creativity of its creators. While we never got this game, its core concepts—time travel, reality balancing, and player-driven paradoxes—have inspired many subsequent titles. For fans of RPG history, it’s a delightful peek into a world that almost was, and a reminder that the best ideas often come from the most audacious what-ifs.
