I never understood how "Winter Wonderland" got first place in '99. For a puzzle-piece it does have it's charm, and it is very well implemented, but I found the map flat, and mostly just unsatisfying, the character interactions were shallow and grating. The treacle story and prose have been commented on in other reviews, and indeed, it only exasperated my distaste for this one.
This might be of interest to puzzle aficionados and children, but probably too difficult for the latter and bit ordinary for the former.
