OpenAI at the Dota 2 World Championships
So an interesting thing you could do as a game company with an "unbeatable" bot is to use it to balance a metagame. Let the bots all play each other and tweak character stats etc until they win a proportional amount of the time. (This presupposes that the bot learns the game the way OpenAI claims it is, without needing to learn from player replays or from playing in a very different way than human players do with tree search etc)
