# The Thread: "We're Using AI"

Over October 18–19, Stirrup turned a weekend experiment into an industry-wide argument: he vibe-coded a basic football/soccer game in Unreal Engine with an AI agent connected through MCP — the agent testing and iterating on its own — then argued studios planning five-to-ten-year roadmaps without AI are "planning for a fake future."

## Key facts

- "I vibe coded a bad but improvable game in two days and I only spent 3 hours actively" — Stirrup, who said he had never attempted to make a video game before.
- The prototype was built in Unreal Engine connected to an AI agent through MCP; he posted a recording of the agent testing and iterating continuously.
- "Gaming is the only industry slow-walking the transition because users have negative sentiment." / "Users want the truth. We're using AI."
- To one commenter he conceded that having a "human in the loop, exercising the judgment" is "mandatory."
