I just did the same thing. It sent me on a campaign to recover an ancient artifact, but it played out the whole scenario for me without stopping to ask what decisions I would make, and there was zero conflict along the way. Nice descriptions of the forest and labyrinth my character had to navigate though.

I did this a couple of weeks ago. At first it refused, saying it was just a language model or something like that. I said "go north" and it just started up a game.

I also tried to get it to play a game of Rogue for me w/ the old ascii graphics, but it held firm in its refusal on that one.
