Which was better? I vote for DK, but it's close - they're both incredible (and they both have terrible sequels).
I'm playing Theme Hospital through again at the moment, but I'm slightly stuck - I've got through to about level 6, then when I finish it it's sending me back to the level before (the one where you've got three consultants and you need to train up the rest of your doctors). I remember getting around this problem back in the day, but can't find reference to it anywhere online. Any help?
