Hey, thanks for the reminder; I loved the premise of the game so I think I'll hype it up.
First off it's "Picassio," yes with an I. And its not as boring as art-theft, it's competitive art-theft. You have to contend both with gallery security and another theif. You'll (and likewise the other guy) have plenty of fancy hi-tech gizmos you can use to aid you or also use the other guy's gizmos that he left lying around (and vice versa).
