Just play the games yourself.
But it's fun. I used to watch Civ IV/Civ V playthroughs with all players being bots and it was weirdly entertaining, especially when you made "bets" who would win based on start / AI personality. Also, the one that's been doing that would write writeups based on that.
It is entertaining, just in a different way.
It's like watching an ant farm or fish in aquarium: a different kind of entertainment.
Could be fun - will the AI model get stuck on the same things I did? How does it overcome obstacles? Will it try to break the game to power through?
