Sacred is a game that I reviewed a while back. I felt (and still do) this it was a very good product, but was unsure of whether or not it would have the longevity required to see it reach a true level of success. Flash-forward: Sacred’s first official expansion is Underworld, and I have just finished logging too many hours to mention. So, is this expansion worth a few extra gold pieces from your vast stores of wealth? I think so, but please read on and decide for yourself.
