Universe Sandbox 2022 Retrospective

We’re excited about our plans for 2023, including adding more materials to planets as well as improvements for our physics simulation, but we’ll dive into our roadmap in an upcoming post. First, let’s reflect on some of our accomplishments from 2022.

New team member

Last year, Conrad joined the team as our User Interface Engineer. Since then, Conrad has been adding interface controls for object customization, fixing general usability issues, and helping to make our user interface easy to use on small screens in preparation for Universe Sandbox on mobile.

New guides and fly-by simulations added to Universe Sandbox in 2022

We added new guides on object customization and a simulation of NASA’s DART mission. This ambitious mission tested humanity's ability to deflect asteroids away from Earth by intentionally crashing a satellite into an asteroid and accurately predicting the change in the asteroid's orbital period.

Preview versions uploaded in 2022

Your playtesting of our preview versions (previously called community test builds) gives us valuable feedback for improving features in active development. A huge thanks to our wonderful community for all their help.

571

Highest number of concurrent users in Universe Sandbox in 2022

The highest number of concurrent users we’ve ever had was almost in 2022: 648 on December 24, 2021. We’ve already beaten the highest number this year, but you’ll need to wait for the next retrospective to see it.

1,801

Positive Steam reviews in 2022

We’re truly humbled that we are still rated “Overwhelmingly Positive,” both recent and all-time on Steam (over 96% of reviews are positive). Your support and feedback are truly appreciated and help make Universe Sandbox even better.

1,862

Code commits, or changes, made to the Universe Sandbox project in 2022

The most code commits occurred during the week of May 8, when 65 commits were made. While a single commit can be as small as fixing a typo, some of them have been whole new features.

7,735

Files uploaded on our team messaging app

These are files we share with each other via Slack and include screenshots and videos of features in progress, log files for resolving issues, and astronomy jokes.

Discord users on our server at the end of 2022

It’s great to see your creations and constructive discussion on our server, which has grown by over 22.5% in the last year. Join us on Discord.

9,253

Simulations shared in the

(https://steamcommunity.com/app/230290/workshop/) in 2022

That's more than 25 simulations shared every single day! You all continue to use Universe Sandbox in ways we could never have imagined, and we can’t wait to see what you make next.

74,257

Messages sent on our team messaging app

Giant Army has been entirely remote since its founding in 2011, and with 13 team members across 3 continents and 6 time zones, messaging on Slack is how we get most of our work done.

Times the Welcome to Universe Sandbox guide was played

Whether you’re a new player or just wanted to check out the reimagined welcome guides we released last year, we hope you enjoyed learning about the beauty of our universe. You’re using that knowledge responsibly, right?

911,241

Times the Planetscaping tool was used in 2022

Letting you shape and customize planets is integral to the spirit of Universe Sandbox, and we’re glad you’re experimenting with the power that comes with it.

Times supernovas went off in Universe Sandbox in 2022

Astronomers estimate there will be 1 supernova in the Milky Way every 100 years. They also think there are about 100 billion galaxies in the universe. Assuming all galaxies have a similar number of supernovas to ours, there are about a billion supernovas in the universe each year. We got about 0.1%* of the way there in 2022. Let's see if we can get closer in 2023!

*Thanks to Steam user Nantes for pointing out that the original value of 1% was wrong, and this should be 0.1%

2,007,301

Times the top played simulations of 2022 were opened*

The top 10 sims of 2022 were:

Rank	Simulation Name	Times Opened
10	Saturn with Rings	129,522

Times the Force tool was used in 2022

Whether you were giving planets a gentle nudge, slightly adjusting their rotation, or spinning them apart, we know you were forceful in your efforts.

6,265,426

New simulations were created in Universe Sandbox in 2022

That’s about the same number as last year, with a new simulation created every 5 seconds.

35,802,793

Times a simulation was played or paused in 2022

By far the most popular thing to do in Universe Sandbox in 2022 was to play or pause a simulation. That’s about once every second.

What’s Next?

More materials for building planets and their atmospheres, physics simulation performance improvements, non-star objects emitting light based on their temperature, and more are in store for 2023. Be on the lookout for our 2023 Roadmap, which will have more details about our plans for this year.

This is a work in progress

And Most Importantly…

Thank you. Your continued encouragement and support let us keep simulating the universe more realistically year after year. We are so grateful for your suggestions, feedback, and kind words. The simulations you create continue to impress us, and we want to continue improving Universe Sandbox to expand your creative (and destructive) capabilities. There’s so much to do, and we can’t wait to do it!
