Yea, they've released clean - without any extensions like Deeper Dungeon (that I've never played :/) - DK I about end of 2011 (November I think...).
Now I see that DK II is buy-able in the same price as DK I. Both version are hard to work on windows 7, but... it isn't unforceable!
I have the Dungeon Keeper gold cd but the installer wont run at all but i manged to get the keeper fx 0.39.exe from the http://mystic-gamers.org/keeperfx/ but the download rate is shocking lol so im hopeing it works
Edit:This works great sooooooooooooooooooo happy! i get to play DK1 again everything pluse more is on it
