Linden Lab Adds Wizard of Oz Content to Blocksworld
Linden Lab has also secured other relationships to bring world-famous brands to Blocksworld (like the recently released Transformers sets). Blocksworld has seen more than 1 million downloads and more than 600,000 user-created worlds shared to date.
Updates with well-known IP should boost the game's userbase even more. And the fact that Linden Lab is still updating Blocksworld with licensed content suggests it's still growing and/or earning revenue.
