Redditor uses coding agent to finish an obscure 18xx Pennsylvania railroad game

Reddit user natep1098 wanted to play an obscure Pennsylvania railroad 18xx board game online, so he fed the rules and an unfinished 18xx.games implementation to a coding agent.
After several token-limit resets (on a Plus subscription), he was playing his fork in the browser, with hotseat multiplayer supported via the 18xx.games codebase. He plans to share instructions for private launches, publish a link, and submit the project for peer review tomorrow.
