This is even mor difficult then the other topic.
Probably the one that comes to mind is Elder Scrolls IV: Oblivion, it is so good that I have had to create multiple character to experience it, for one there is so much to explore, from characters to envirments to items/loot, and the controlls were not too bad as you could play how you wanted. Of course there are quite a few bugs, but everything else was so good.
