We use ML for the AIs in our digital boardgame adaptations on Steam and phones. Our Race for the Galaxy AI is better than 97% of our players and our Dominion AI (still in beta) is at about the 75th percentile. Not only is it good at the games, it's super adaptable when a new expansion comes out or the designer adds errata for cards. Finally, it's been helpful with the design of new cards. A quick training session and we can put the cards in front of the designer and they can supplement their play testing. The AI has even found some 'exploits' that new card combos create that we can address before release.
