It’s difficult to imagine a RPG bot.
during my time, there was an MMORPG called Ragnarok Online and I remember there was an bot that can be scripted to follow specific route to do item/exp farming, go back to the town when the inventory is full, and also can be programmed to avoid other player. Maybe with AI, the bot can be told just to perform similar thing by just using prompt? Or at least it can be made to perform like human?
