American McGee's Return of Alice Gets Creepy Stop-Motion Trailer

The recently-announced sequel to American McGee's Alice now has a ballpark release date - it'll hit in 2011 - and a slightly unsettling "unofficial" trailer.

I'm not quite sure what exactly it is about Alice in Wonderland that pings the creativity of others, but sometimes we do get some awesome stuff out of it. Whatever else you could say about 2000's American McGee's Alice, you certainly can't say it doesn't have a sense of style. If this trailer is any indication, the upcoming Return of Alice - first revealed in a blog post back in February - will follow in its footsteps.

Or maybe it's just that, as things like the music video for "Sober" by Tool demonstrate, the stop-motion style of animation makes already-creepy things that much creepier.

Here's the one thing I don't get, though - the post on American McGee's Twitter that announces the video and points to the game's new website refers to it as an "unofficial" trailer. I could understand if it was, say, a version cut together by a dedicated fan from pre-existing footage, but this is the first real video we've seen of anything having to do with the game. It's linked to on the official website. What could be unofficial about it?
