I'm not sure about expanding domains, but I expect that very close to 100% of games are now using LLMs to a very significant degree during development, even if most won't admit it. The "AI disclaimers" for games need to go away, simply because it's just rewarding and incentivizing lying and punishing truth.

yes we're working on it! trying to push a few open world rpg games with real economy and game design. it's also super interesting to benchmark the current models' capability in this direction, since this is a naturally hard and multimodal coding task
