Creatorverse
Creatorverse was a physics-based sandbox creation game for the Apple iOS, Android, Kindle Fire, and Kindle Fire HD that was released in 2012. The product was discontinued in February 2014.
Creatorverse gained notoriety in the gaming press as the first tablet app released by San Francisco-based Linden Lab, which had previously been known primarily as the creator of the online virtual world Second Life. The product continued the company’s positioning as a maker of “shared creative spaces” that favor open-ended content creation and sharing over traditional goal-oriented gaming.
