so first off, if anyone wants to buy legit signed copies of any of my games they are usually always in stock here. http://edplusdanielle.bigcartel.com/product/3-signed-game-pack
currently the only copies of my games in print are the ones published by headup, mostly in Germany (but also the UK and sometimes in Australia) the 1st publisher we had was a US publisher that published only SMB, the box had a mat finish with gloss only on meat boys eyes and teeth and had an american ESRB on the front. these were sold for a limited time in target, walmart and Frys but have been sold out for years. the US publisher never paid us and still owed us 8k before they went under a few years back.
so if you own the US one you have a rare copy of the game, the german version features more physical content inside (post cards and the like) i believe the US version did feature a small pull out poster inside the dvd box.
