Jon Radoff spent six months coding Legends of Future Past in 1992. Last weekend, he brought it back from the dead in about 48 hours. He fed Claude Code a pile of 30-year-old artifacts: script files in a custom language he'd invented at nineteen, plus a GM manual from 1998 and a gameplay capture from 1996. No source code. The AI agent reverse-engineered the scripting language and parsed the combat formulas. Then it rebuilt the whole thing. A Go game engine, React frontend, WebSocket multiplayer layer, MongoDB persistence. Deployed to Fly.io. Done.
Legends of Future Past earned Computer Gaming World's 1993 Special Award for Artistic Excellence. It had one of the earliest crafting systems in online games, skill-based progression without level caps, and paid Game Masters running live narrative events. Alumni went on to work on Star Wars Galaxies at Sony Online Entertainment and founded studios like Worlds Apart Productions and Dejobaan Games. Wikipedia credits the game with introducing "some of the top talent in the MMORPG industry." It launched on CompuServe in 1992, moved to the open internet in 1994, and shut down December 31, 1999. For 27 years, it simply didn't exist.
This matters beyond nostalgia. The Video Game History Foundation reports that 87% of classic games released before 2010 are no longer commercially available. Multiplayer online worlds are especially vulnerable because they only lived on centralized servers. When those go dark, the game vanishes. WildStar, The Matrix Online, The Sims Online, all permanently lost. Some communities have kept games alive through emulators and private servers, but that requires dedicated effort and technical skill that most lost games will never attract.
What Radoff demonstrated is a different path. You don't need the source code if you have enough artifacts. An AI agent can parse old documentation and decode custom scripting languages. It can reconstruct a working implementation from fragments. Radoff is clear this wasn't autopilot. He describes it as "directing a tireless, brilliant collaborator who needs you to stay in the room," providing context and making judgment calls throughout. But the compression is real. Six months of original development compressed into a weekend of agentic coding.
