We're surprised the issue didn't come up sooner, but according to tweets from Peter Molyneux, one reason his "experiment" Curiosity has been delayed is that the name is already in use, by ... some government program or whatever.

"Humm there is a problem with the name Curiosity," Molyneux tweeted. "We can't use it because of NASA. I wonder what one word would sum up Curiosity: The Cube." He plans to tweet the best suggestions from the @22Cans account.

As the team (and the collective mind of Twitter) brainstorms, we'd like to offer one warning: don't just change it to "Qriocity." For some reason, that's already in use.

Update: Molyneux told Modojo "The name change is prompted by the need to have something simple to search for in Google. This worked well for 'Curiosity' but since NASA: Curiosity is now obviously generating a lot of interest we need to change the name." In other words, it's not a trademark concern or anything like that, just in the interest of avoiding confusion.
