For me, the AI is best used for ideation and variations more than it would be for actual product creation. Yes, sure, you can make art and sound and other things, but the tricky part is to obtain consistent flow which is expensive and hard to preserve in context and story.
If you are still willing to try, though, i'd go with simple games like quiz (brand logos, or cars, or something catchy and trendy) and see how much reaction you would get.
What do you have in mind?
