Limbo...a game...a place...infringement?

This story has been developing over the last few days. There's a point-and-click game called Limbo of the Lost which appears to have ripped off, well, quite a few games' art and/or model assets. There's a forum thread with comparison shots.

I'm all for relaxing restrictions with regard to copyrights (seriously, life + 75 years? 90-ish years for corporate works? outrageous) but this is most definitely not fair use.
