The questionairre seems legit - it's on the Nielsen website, and I doubt a hoaxer would bother coming up with all those dumbass questions.
It just seems extremely odd that a game that nobody has heard of would be revealed like this. No press. No mention of it on the Lucasarts site.
And, like I say, there's no way Lucasfilm would be happy to see their Star Wars logo, and Star Wars character material, out there with no (r) or TM or (c) notices.
Very, very strange.
