IdleRPG in IRC was also great fun.<p>I've tried writing my own version, with significantly more ambition, but got hung up on two issues every time:<p>1. Overly ambitious! I wanted it to be a general API, so that you could hook up Slack, IRC or Discord to it.<p>2. I wanted users to give their idle avatars goals, or be able to interact with the game despite it being mostly idle (e.g., "go this way", "be aggressive against everyone you meet", "try to avoid danger", etc.), but didn't have a great way of processing those instructions in a way that meshed with the "tick"-based processing of everything else going on with the game.
