Greenheart Games Pty. Ltd.

Greenheart Games was founded in July 2012 by brothers Patrick and Daniel Klug with a mission to develop games that are fun to play rather than mind-numbing money grabbers. Less social, less ville, more game is our motto.

Our focus
Our focus is on creating good games. We prioritize entertaining and engaging gameplay over revenue-generating mechanics. We value the player’s time, as well as intelligence, and we strongly believe that games need to be more than dressed-up slot machines that abuse human impulse to extract money. This means that we sometimes go against industry trends, especially in the mobile arena. We are also more than a little wary of the emerging trend for perpetual crowd-funding, and early access campaigns on PC.


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.

Dave McCabe (Narrative Designer)

Dave has been writing for too long to recall, but he wrote his first video game story in ’97 after playing Final Fantasy 7.

He still hopes to makes ‘Robot and Girl’ some day…
He is not really a drawing. He is, however, un-photogenic.

Seth Trimble (Art Wizard)

After dabbling in robotics, 3D printing, and setting things on fire with a blowtorch, Seth figured “why not make game art?”. And so he did. After three and a half years cutting his teeth on mobile games, he concluded life was too short to live in Dallas, packed up and moved to Oregon – where they get the green mana for M:TG. He now spends his days painting, sculpting, and concepting fantastic characters and the worlds they inhabit.

Favorite games : League of Legends, Super Meat Boy, Crawl, Super Smash Brothers, FF 1-9, M:TG

Mike Singleton (Art Necromancer)

Mike has been making art since he could hold a pencil, with a special preference for the Robot, Monster, and Spaceship genres. After getting his start as a comics author and freelance artist, he served a three-year tour in the grim trenches of the mobile games industry. Now an older and wiser man, he’s finally fulfilling his longstanding dream of making games for the PC.

Favorite Games: Jagged Alliance 2, Supreme Commander, Angband, and Deus Ex.
