Creatorverse from Linden Lab is now available in the iTunes store here, for $4.99 (which is pretty steep in a world of free iOS games and in-app payments, but there you go), and hardcore gamer site Kotaku loves the 2D sandbox/physics-enabled sandbox building game, dubbing it "One Of the Coolest Things You Can Do With an iPad". So there's that. In an exquisite irony, I don't own an iPad at the moment, so my personal take will have to wait a month or two. If you get a hands-on look now, please share your take in Comments!
