I got the visit of an English guy on DK.net that told me something extremely interesting.
On the AssemblerGames forum, someone sells something extremely rare: four beta versions of Dungeon Keeper 2 at the price of $150 US. If you wanna see the post by yourself and perhaps even buy those copies, you must register to the AssemblerGames forum first and then get there.
As a proof, here are the four pictures of the discs:
I'd like to buy the discs myself, but unfortunately, I don't have cash. If someone here is rich enough, this is a REAL OPPORTUNITY that shouldn't be missed!!!
