Since I honestly don't know enough about this topic, it would be nice if you can mention the other companies. I just mention OpenAI because they are a prominent organization which happen to have both open and AI in their name.

Maybe I am also not being very clear, but I am actually visualizing a game which is popular enough to attract a lot of gameplay, but has gameplay elements which are actually the kinds of things which the AI problems are trying to solve. E.g. imagine capturing gameplay from a popular multiplayer drone game to improve drone navigation.

Drones apparently don't fly very well autonomously.

Now, imagine if it were possible to get open data where any researcher or group could work on this problem using a gameplay dataset. Perhaps someone with an unexpected take on the problem could make some important contribution?
