Its hard to put down exactly what I like. It is spooky king aruthor that plays like oblivion. It is clear that the studio is new and doesn't have the big budget a AAA studio. But man, this game just clicks. I like that the builds can be mixed and matched. But once you find a play style you like you tend to settle down on it.
KDC has a learning curve. You need to understand what the game wants of you. But once you do it becomes an amazing experiance. This is one of the few games I have taken the time to 100% complete all the achievements over any number of run throughs. There is a large modding community available as well that is still coming out with updates and new mods 6 years after the game release.
