Yes thats it boys and girls ive just finally completed every posible achievement of the game. I did the main story relatively quickly then went on to be the grey fox, master of the fighters guild, arch-mage of the mages guild, Listener of the dark brotherhood and a knight.

Im wondering though if there are any more un recognisable quests I may have missed. its weird it feels like yes im all power I have everything but there is no evident ending, just a continuous game. A sad time that its now I think at an end!
