Tldr; A game with decent graphics and many nice features. Very large with a huge amount of content and playing hours. However such a huge world has it's content spread out pretty thinly leading to mindly hacking and boredom. A pity as some of the features and gameplay was fun.
I feel that I am short-changing this game by only giving it 2 stars, however when I compare it to other games on GOG, I find it hard to give it more than 2, after all even the worst games on GOG are still quite playable.
Another reviewer said that Sacred is like a cross between Diablo 2 and Morrowind. While they use this analogy in a positive light, I use it in a negative. The game does not have as good of a story as Diablo 2 or quite as addictive gameplay. Nor does it have as interesting character development (ha) or combat as Morrowind. Some may very well enjoy this game, but I personally found it too open and rather uninteresting, which is a pity. If they had made a smaller but more content filled world this could of been very interesting game but as it is, I got bored after riding a horse around for several hours completing one meaningless quest after another.
