This doesn't seem to have very good reviews on HER forum posts but I am LOVING it.
It's chock full of codes and cyphers which I don't find at all easy but enjoy doing.
The setting alone generates an atmosphere of potential jeopardy. I play it with the lights out!
So far, for me, it's at least as good as Shadow at the Water's Edge, which was the best ND game in a long while, i.m.o.
Anyone else love this game?
