You may think I am ridiculous, but I am giving this game a 10 simply for the sheer enormous amount of time I spent playing it many years ago growing up.
Geez, this is the game that turned me on to adventure games. The thrill of finding what to do with the flute, what to do with this room... etc... I remember being so exited when I found pandora's box after hours of searching only to find I wasn't near the end.
That was over 15 years ago... now thats gotta be a damned good game for me to remember.
