ACHIEVEMENT REVIEW
Difficulty: 3/10
Time to complete: ~1 year or ~8765 hours

Universe Sandbox Legacy is a universe sandbox game where you can play around with stars, planets, physics etc.
The game is old and it does show from time to time. I personally had an issue where the game would put itself on top of other windows after playing another game in fullscreen, requiring me to restart the game.

It has easy misc. achievements but the most notable achievements are: Starting the game 10 000 times (scriptable, link below) and idling in-game for 1 year.

General tips: Clicking the "Options" button in-game pauses the simulation (idling time still counts when paused), possibly saving some resources on weaker systems.

There is another version of this game called Universe Sandbox Legacy - School Edition, which you can get a free key for by messaging the devs on Facebook [www.facebook.com]. Both versions have the same achievements and use the same files so the achievements you have unlocked on one version, will auto-pop when you launch the other version.
