I honestly couldn't tell you the differences between the reprint from a little while ago and the original, but this is straight-up the original 2006 run. It was played, and then we moved. It stayed in a box that was lost for a long time and I recently uncovered it and found this game. If there are any differences and you're a collector, you can rest assured knowing this is the real deal.
*edit* a quick cursory bit of research shows that the boxes/cases are different from the original print and the reprint.
