Tavern Keeper is a fantasy simulation game that allows players to manage a pub, featuring extensive animations and user-friendly item design tools. It was released on Steam in November after over a decade of development, during which six versions were created. The game includes an interactive audiobook-style story system with RPG-like dialogue choices. Greenheart Games explored various systems that did not make it into the final game, including a quest system involving heroes, which was ultimately deemed disconnected from the tavern theme. The game incorporates complex mechanics such as temperature effects, food spoilage, and cleanliness impacting the tavern's atmosphere. The development process faced challenges, particularly in achieving a fun gameplay experience, which took several years to realize.
