It is stunningly amazing! With the scenario generator, I was able to get it to propose plausible solutions to real life problems. It even suggested possible ways to cure the COVID pandemic, that made sense and were at least in some ways plausible!
It is also a lot of fun to play with fictional scenarios. I even simulated my own Planetary Settlers game inside AI Dungeon, and that was fun too! It came out significantly different than my actual game, but it gave me some ideas for improving the game! I highly recommend this for uses that go beyond just the game play aspect. Do take it with a grain of salt though, like humans, it isn't right 100% of the time!
