If you don't mind me asking, what issues do you have with it so far?
Also for people with the game; how is the quest structure? Are they robust?
Depends on the quesat you get and the quest you are doing. Its usally involves asking someone to gather clues and information about the whereabout and then going there to use your witcher sense and then slaying the beast. Others involve collecting items that the npc requires . There are ? in the game, which are random moments which allows you to explore and gain even more quests. Those far, involve killing monster and assisting th enpc bieng attack. that can lead to more questss and adds more story . There are even quest wher eyou are just investigating clues or evidence laid around the area of interest.
