Evaluation
Universe Sandbox Legacy (the original Universe Sandbox, App ID 72200) is no longer available for purchase on Steam — it has been removed from the storefront. This effectively makes it delisted. The reason is clear from the developer's own communications: Giant Army launched Universe Sandbox ² (a separate Steam product, App ID 230290) in August 2014/2015 as the full sequel and successor to this original version. The last developer news posts for this game, dating to August 2014 and August 2015, announced and promoted that sequel rather than any updates to this original title. The original game has since been retired in favor of its successor, which is where Giant Army has directed all ongoing development.
Evidence
Developer announced Universe Sandbox ², the sequel, is now available on Steam, directing players there instead of the original.
Developer announced Universe Sandbox ² alpha is available for purchase, describing it as the successor built with improved physics and ongoing future development.

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.
