Technical things first: I'm playing this on windows 7 (64 bit). I played 6 hours so far and only had 1 crash when i started a new level, I then just restarded the game and loading just worked fine. I haven't encountered any graphical issues or else. About the game itself: I've never played Dungeon Keeper, so i'm not connected to it by nostalgia or something. Yet, i really can enjoy the game. And if such an old game is enjoyable in times where we got graphics like those of BF4 etc., it shows that Dungeon Keeper is just a very good game (this also says that today's games are often - let's say very bad - concerning gameplay itself, but that doesn't belong in this review). Conclusion: Game great + works in Win 7 (64bit)
