Having just finished the game, it gets a thumbs up from me too!! The storyline isn't as strong as say GK2 and you don't get much interaction with the other people around but just enough to keep the story flowing. All the teenagers who have visited and seen me playing are stunned by the quality of the graphics - they are comparing with such as World of Warcraft and guild Wars. if it makes em adventurers, its worth it!!
What I did like is that each of the characters has a bit of good and bad in them, making them more realistic, rather than being squeaky clean like some we come across.
I only had a couple of Duh moments when I got stuck, but it was usually a stupid oversight on my part
there is a sound puzzle in the game, but as we had a houseful at the time, I did it cold and still managed it with a little trial and error. There is also a colour based puzzle, but I'm sure the shades of grey to a visually challenged individual will give the right tones. If not, ask for help, don't dismiss the game because of one puzzle!!
One for a replay definately!!!
