A few times, playing Outer Wilds has come up, and it could be great both because it's an incredible game and that it would be neat to have Neuro be the one focused on actually figuring things out.
The problem is that progression in Outer Wilds is entirely knowledge-based, so if she knows things from her LLM it might skip a lot of the game, both puzzles and secrets that are meant to be learned elsewhere.
A good test might be asking "how do you get the launch codes in Outer Wilds?" with Google off after suggesting that knowing would make her smarter than Vedal. (That's in the tutorial so not really a spoiler)
