But LLMs are terrible at text adventures too. See e.g. https://entropicthoughts.com/updated-llm-benchmark and previous articles referenced in there.
I have yet to see any sort of harness that lets a frontier LLM interact with a text adventure and make meaningful progress on its own.
They are also pretty bad at navigating mazes (which can be somewhat similar in spirit to text adventures where you need to navigate through text): https://arxiv.org/abs/2507.20395
