Reviews

“This is where Universe Sandbox succeeds brilliantly: players experience godly power to create or destroy, while almost unavoidably learning something about the physical properties of our universe.”
87/100 – PC Gamer

“Using the vast range of variables and tools at your disposal you can create some enormously convoluted displays of physics, bending cosmic laws to your will...”

Universe Sandbox ² Now Avaliable

Universe Sandbox, originally released in 2008 and on Steam in 2011, is no longer in development. We encourage you to check out our long awated sequel, Universe Sandbox ², now on Steam Early Access!

About This Game

Create and destroy on a scale you've never imagined with the ultimate space simulator.

Harness the power to create black holes, collide galaxies, and manipulate gravity with just a few clicks. Inspired by the software astronomers use to unlock the mysteries of our universe, never before has astronomy been so interactive or so much fun.

Spawn a massive moon to tear apart Saturn’s rings or launch a rogue star to rip the planets from their orbits around our sun. After unleashing catastrophic destruction, create your own solar system and share it with friends.

This is a simulation...the achievements are the game :D
PS(1) : No need for 10000 hours to get 100% the game is made to be bypass :P
PS(2) : use a script for the startup achievements ^^

When you run a simulation of earth and the moon, and change the time perspective to 1 year per second, the moon is gone before you can blink. Seeing how the moon will still be here in a year, there is clearly something wrong with the physics calculations in this program. And if that's the case, why bother?

I bought it because I was curious about modeling my own solar system, installed it and tried it then I realized I have spent in a blink of an eye at least 2 hours playing God.

It's pretty fun to see different parts of space and see either how they work without messing with them, but the best part is seeing how you can change things and overtime how that would change the universe. There are some built in interesting scenarios, like the solar system, the collision of Andromeda and the Milky Way, and I think there are a few others I can't remember. You can change the size or density of certain objects, introduce new objects, and just generally play god with the universe. There aren't a million things to do, unless you want to do the same things in every area you see, but it is definitely fun to just see it and learn how it all works. It's like physics and astronomy class put into practice.

One thing that came to mind was that when I was interested in achievements, this game has completely unobtainable and irrelevant achievements. There all time played based and it's things like play for a day, play for a week, play for a month, etc. I think there are some other ones, and you can get some ideas of things to do from that. Of course steam achievements are useless and there's no way to track them, so it doesn't matter unless you really absolutely need to get 100% achievements in all the games you play.

What can I say?

1 hour of gameplay to explore the universe and get 12 of 16 achievements.
10000 hours to get the final 4 achievements AND become extremely good at doing nothing, seeing only the endless nothingness that exists in space, endeavouring to explore strange new worlds but seeing nothing, going where no man has gone before ..... wait .... that has already been done. There is nothing to see in our universe ...... NOTHING.

11/10. Would do another 10000 hours to finally see something.

When I say that I'd reccomend this game it's only to a small niche of people. Because I happen to fall in the niche I rather liked Universe Sandbox, though I can see where many people woud not. Universe Sandbox is pretty self explanatory in the title, its a astrophysics sandbox in which you can create and destroy solar systems, galaxys, or even galaxy clusters (if your computer is beefy enough) Many stats and attributes are tracked as you simulate the astral dance of heavenly bodies.

Things like density, spin, velocity, mass, and heat are all tracked and simulated to give you the most realistic expierience possible. Unfortunately, it doesnt get very realistic. My biggest gripe I would suppose is the physics. The game uses Eular math, or if you have a processing power Runge Kata. But eventually stable orbits will do someting completely random, sending a few planets and stars on random vectors straight out if your little "pitri dish". This doesnt bother me too much because it mostly only happens when it comes to simulating galaxies. On the solar system level it does quite well and it has enough options to accomodate nearly any computer's processing power. That is, if you can navigate the menus.

Theres lots of options and statistics for every celestial body and you can edit every fascet. the problem is, this creates a very confusing series of menus, with confusing abbreviations and volcabulary if you're not already familiar with scientific notation and units of measurement. If the menus were a bit more friendly I think it would open up this game to alot more people. The actual simulation field can be a bother to wrangle too. I found it sometimes likes to snap focus to nearly every other celestial body but the one I want to focus on. The "searchbar" at the top ended up being my best friend.

If youre like me, and you can wrangle the menus and put up with the sometimes sketchy simulation, it truely is a universe at your fingertips. This simulator will only take you as far as your imagination (or processor) will take you. Binary systems, rings around Earth -- have you ever wondered what it would look like if the earth had a ring then the moon crashed through it? The possiblities are more or less limitless, given your computer can handle the math. If youre into astronomy, physics or just enjoy space to any degree, this game is worth checking out.

Without an actual objectives or things to accomplish, this game falls short of actually being a game. It would be better described as an app. This one probably isnt right for the masses, but just right for the armchair astronomer in me.

Destroyed the earth with a sun sized teapot.

I also made the earth orbit around Gabe Newells head.
