This game was largely over looked when it came out, so I don't think it got a particularly large print, at least not in the small-box. Also, the more expensive one that the OP mentioned might be the 'butcher knife' box cover, which was pulled from shelves and replaced, so it is harder to find now. There also was apparently a budget jewel case release at some point, too. Even that sells for a bit.

People seemed to realize what a gem this game is about 5 years ago, and that's when prices started going up. There probably is a little bump right now because of the movie release, but it was high before the movie, too.
