"EU launch is not until 2013, unfortunately," creator 5th Cell confirmed on Twitter.
Posting on a NeoGAF thread, a developer from the studio also rejected suggestions that the delay is due to localisation issues: "It's due to stuff I can't talk about until 2013," they said. "Scribblenauts and Super Scribblenauts were released NA and EU the same day. Trust me. I want your money. It's due to things outside of development."
Asked about the nature of the delay, a spokesperson for publisher Warner Bros. told Rock Paper Shotgun: "Details about the European distribution of Scribblenauts Unlimited are coming soon."
