Yeah, I do these sometimes. Like https://gwern.net/doc/design/2026-09-17-claude51fable-thepur... or https://gwern.net/doc/reinforcement-learning/safe/2026-08-16... or https://gwern.net/doc/ai/nn/transformer/gpt/claude/4/2026-02... . Usually they aren't playable, though, although I have some prototypes of _Goodhart's Garden_ I need to playtest a bit for feedback.
