10 Year Anniversary Celebration

People from around the world gathered at our HQ to join in the celebration. It was heartwarming to see fans, colleagues, and supporters coming together to mark a decade of innovation, exploration, and creativity. 

For those who couldn't be here, we made sure you didn't miss out. Our live stream ensured Space Engineers across the globe could be a part of the festivities. The evening featured presentations from our CEO Marek Rosa as well as from our talented colleagues Jan Hloušek and Natiq Aghayev, offering insights into the development of Space Engineers over the years. 

We couldn't forget the live orchestral concert featuring Space Engineers' music from our amazing composer Karel Antonín. It added a special touch to the evening, taking us on a journey through the game's universe. Of course, we had great food, and there were plenty of opportunities to meet and chat with our fans, supporters, and the brilliant minds behind Space Engineers. 

We are immensely grateful for your support, which has made Space Engineers what it is today. As we reflect on this memorable September event, we're excited about the future. Here's to more years of exploration, creativity, and possibilities!

Sounds of Space Engineers 2023

After an overwhelming response featuring more than 100 submissions, the top 15 tracks of the 2023 Space Engineers music competition have been selected by multiple judges at KeenSWH!
It was no easy task selecting these winners as there were many high quality and unique entries.

The judges tried to select a mix of music styles so that there is variety and hopefully something for every player to enjoy! All of these tracks are making their way into the Jukebox in this update. 

Enjoy listening to these amazing tunes!

Personal bio:

Marek Rosa is the founder and CEO of GoodAI, a general artificial intelligence R&D company, and Keen Software House, an independent game development studio, started in 2010, and best known for its best-seller Space Engineers (5 million copies sold). Space Engineers has the 4th largest Workshop on Steam with over 500K mods, ships, stations, worlds, and more!

Marek has been interested in game development and artificial intelligence since childhood. He started his career as a programmer and later transitioned to a leadership role. After the success of Keen Software House titles, Marek was able to fund GoodAI in 2014 with a $10 Million personal investment.

Both companies now have over 100 engineers, researchers, artists, and game developers.

Marek's primary focus includes Space Engineers, the VRAGE3 engine, the AI Game, and LLM agents that learn continually.

GoodAI's mission is to develop AGI - as fast as possible - to help humanity and understand the universe. One of the commercial stepping stones is the "AI People'' game which features LLM-driven NPCs grounded in the game world with developing personalities and long-term memory. GoodAI also works on autonomous agents that can self-improve and solve any task that a human can.


  1. All this is nice and all, but you should practice more self criticism rather than glorifying yourself endlessly. No bug fixes. No improvements. Other games have events on regural bases. New content, special events, new skins. And countless bugfixes. Take Warthunder for example. All you do is opress people who point out your failures and delete comments and acounts that fail to glorify your insignificant progress. You are the North Kore of gaming.

    1. 1) North Korea*
      2) I'm always fascinated by comments like this one. What's the actual goal here? Is it just "you guys suck"? Is that it?
