Greenheart Games Pty. Ltd.

We are Greenheart Games, a small indie team working remotely from all over the world. We value the player’s time and intelligence and believe that games need to be more than thinly-disguised slot machines optimized solely to generate profit. We made Game Dev Tycoon and you might have heard about our piracy experiment when it went viral. Our newest project is Tavern Keeper, a fantasy tavern simulator that aims to combine tycoon/sim/management gameplay with a fun and funny setting.


Game Dev Tycoon
Our first game to test the waters was Game Dev Tycoon, a business simulation game where you start your own game development company in the 80’s. Game Dev Tycoon was inspired by Game Dev Story (by Kairosoft), which was the first ‘tycoon’ game we enjoyed playing on the iPhone; however, from the start, we wished the game would work and look differently. We wanted a game development simulation which would be less random, more about your choices and a little more realistic. We began working on what would become Game Dev Tycoon in 2011 and created the concepts and game mechanics as well as the game itself from scratch.
Tavern Keeper (in-development)
Our second game currently in-development is Tavern Keeper, a fantasy tavern simulator.
