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.

Why are people getting this game expecting it to have to have the same features and graphics as the second one? If all that was in the second one was in the first one they wouldn't have made a second one, this isn't Madden.
It's a really good game, and a great stepping point from which the sequel was made. You have robust tools at your fingertips, and I certainly had more fun playing this than other space sims I've played in the past. It's far more gamier than a lot of other space sims, but still contains most of the features the other ones posses.
If this one isn't on sale for real cheapy cheap or a gift, just get the second one. It has all this one has and more. If you get this one expecting it to have all the features the sequel has, you're an idiot. (I'm writing this review to attempt to balance all the negative reviews basically complaining that it's not as good as the sequel. Yeah, no ♥♥♥♥.)

Got this game expecting explosions when the planets collide.
They just bounce off each other.

Does anyone know how to get a refund?

0/10, would get a refund if I knew how.

DO NOT GET THE FIRST GAME!!!! THE SECOND ONE IS MUCH BETTER!!!! The graphics suck in this game! If you crash an object into earth, It just leaves a small white spot!!! If you blow up earth, it just splits into smaller earths! In the second game, the collisions are actually realistic, with lava and fragements! Even the gravity is wrong!! There are no animated surfaces or climates or anything from the second game! This game should only be 1-3 dollars! The timestep is confusing, the planet surfaces are ugly, and this is not a realistic game at all!!!

Pros- Nothing that isn't also in the second game

Cons- Bad graphics, horrible collisions, and no climates

Took me some time to figure out how to have fun but once you realize what you can do in-game theres endless possibilities and hours of fun to be had.

Some of the achievements seem impossible to get but diehards with enough time on their hands can get them done.

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.

Universe Sandbox is exactly what its name implies: a place for you to play around with astronomical bodies and see how changing various things will effect the macro-universe. I think it is one of the most unique and awesome titles on Steam. It is well put together, the physics in the game accurately demonstrate real-life laws, and the recent update that puts you directly into a tutorial the first time you start the game really helps you figure out the, at first intimidating amount of, options that you can play around with.

Whether for work, play, or educational purposes, Universe Sandbox is an excellent title that I don't think any Steam account should lack. If you have *any* interest, even a minute amount, in astronomy, physics, or even if you ever wondered what would happen to Saturn's rings if Neptune flew too close, you need to have this game. It's very relaxing to play with, and the the engine is extremely deep - allowing you to truly let your imagination run wild.

The GUI is clean and efficient, and the pre-built simulations and environments are extremely well put together and fun to play with. Some examples include:

*Environments:*
Our Solar System
Local Galaxies
Earth & Moon
Saturn & Moons

*Physics Playgrounds:*
Small Scale Gravity
Floating Moons
Galaxy Collision

Buy now, build your own galaxy or satellite system, and watch what happens as time passes and you introduce variables into the equation.

*Bonus:* You can smash an asteroid into Earth to see what would happen, awesome for those bad days at the office.
