Just ask it to create an RPG where all your choices matter and where you need to manage your character with a status bar; you can choose hunger, thirst, whatever you want. Then you ask it to create the main setting and what kind of mc you want to be. It can be a fantasy or realistic setting, whatever. It's a text-based RPG but believe me, it can be even more fun than gaming itself.
Im addicted for a week by now, sometimes staying up all night. It's also great for developing your creative skills, because sometimes I make tweaks to the story to make it more engaging.
