As I posted at top level, they've already backed off, but even the linked version had a carve out for video games:
(B) Does not include:
...
(ii) A bot that is a feature of a video game and is limited to
replies related to the video game that cannot discuss topics
related to mental health, self-harm, or sexually explicit content, or
maintain a dialogue on other topics unrelated to the video game
It's really hard to prevent a general-purpose LLM from doing those. Especially the last one; any topic unrelated to the game is forbidden, not just the ones you slapped a second LLM on top to monitor for.
