Not one of the quests, including the main quest, were particularly interesting. The characters on the whole were shallow, the story line was shallow and predictable, and worse still, many of the side quests (the much acclaimed content) was fluff. These didnt continue a story or add to any of the other stories in any way.
I liked the idea of wandering into a cave to see bodies and other things, this certainly adds to the feeling of something has happened here, and some random quests were generated in this manner - some of these were great. But you could have done so much more with the stories, especially where decision lines are made, and developing the characters.
Probably one of the worst things about the stories/ quests was the speed at which one becomes the head of the guild, or is accepted into the inner group. It takes a two quests from the companions and you are instantly accepted into the "inner group". Either these people are far too trusting with outsiders, or the story is shallow - i bet the latter.
Come on,i know you can make some advlt depth stories - after all the main people who purchase and play are in their 30s. Creating better stories is only a positive, it will not make anything more difficult to implement, or code, it is about just spending a bit more time on the development.
