Brief

Author @acherm (posted 2026-08-06) reports successfully replicating a single prompt twice to generate two distinct games—a CallOf-style FPS and a FIFA-like game—and then iteratively enhanced both with their 10-year-old nephew. The thread points to a write-up and to Matt Shumer’s GitHub repo 'mshumer/Claude-of-Duty' containing the prompt and generated project.

Why it matters

@acherm confirmed on 2026-08-06 (07:34:09+00:00) that they replicated the same prompt twice: one run produced a CallOf-style variant and the other produced a FIFA-like game.

Key details

  • They iteratively evolved both games with their 10-year-old nephew, adding progressively more features and publishing a write-up and links in the thread.
  • The post cites Matt Shumer (@mattshumer_) and links to the GitHub repo 'mshumer/Claude-of-Duty' which includes the one-shot prompt and the Three.js Call-of-Duty-quality FPS project.
Source evidence

I confirm. I've replicated twice with the same prompt, one to get a variant of CallOf, another for a FIFA-like game. And I've evolved both games with my 10-years nephew with more and more features. Write-up and games' links below. Incredible 1/2

For all of you who think this is fake... here's the repo and prompt (in the thread below) that generated this in one shot:
