Angels in the Outfield
Imagine a concept called "Angels in the Outfield" (named after the movie), an AI-powered “fantasy league” that is more popular than living baseball. You could assemble the best all-time players for each team (ie: all-time Mets roster), and then run simulated seasons each year. You could already achieve something like this through any MLB video game; but to make it good, it would require more than accurate statistics, mechanics, and hyper-realistic graphics, but personality recreations of each player (ie: a convincing first base conversation between Pete Alonso and Joe DiMaggio would be part of the uncanny fascination).
