Just a quick review to say that i, as well as others have experienced the well know bug with this game.
When arriving at the monastary make sure that you fully complete the basic training by defeating Aric.
Dont want to spoil too much ,but for me i fully completed a quest after that and it was still in the current quests tab and no other line of conversation with the other Npc was available,resulting in having to restart the game.
Apart from that i have and still am having a great time playing this as much as i did with Oblivion and The Witcher.
It can be a short game if you follow the main story quests and not do many side quests but you will just find that you wont have much experience and levelling up will take a lot longer.
