It's a beautiful game. I haven't had many bugs myself - a couple of instances, nothing major. The bug issue seems to vary between different individuals.
Actually, if anybody is interested, I bought into this game not really understanding what an RPG is. I'd never played one. I thought it was some kind of medieval sandbox or 1st person Total War. However, I have enjoyed the 66 hours I've played in this game, it's quite good and seems very well done.
I must say though, I am tiring of running around doing these quests to complete the 'story'. I think that is my personal dislike for singleplayer games coming out, rather than a fault of the game. I get sick of being lead around by the nose very quickly. What I am really itching to do is try and play a neutral character of my own invention - rather than that of Henry the investigator. I think it is possible to play this game like a sandbox. I like the idea of playing as a career criminal - burglary, robbery, theft, always on the run from the authorities.
