This one is experimental to say the least.

Because you are the bot and the bot is the player!

Well, more seriously. You are the game master and the bot is the player. You set the rules, create the encounters, the characters and everything. The bot will be your player.

To help you out a bit, I created a fantasy world with elves, dwarves and everything. So the bot should know where he is. But for the rest, it will depend on you (and how the bot reacts to your prompts)

Note: If you just ask the bot to create its own character, it will probably create an evil and powerful elf or human with a war-oriented mindset. So if you want something else, try telling the bot "your character is a good natured dwarf..." or something like "create your character, make him a beastman at beginner level...".
