Best Singleplayer RPGs

Overlord is an RPG.  It does have some RTS elements due to the fact that you have Minions, but it is played from the perspective of your main character, the Overlord.  You should check it out.

Well now this thread is revived I'd just like to add that I agree with Yaas. I only just picked up the Gothic series this year and they are all really really good games once you get used to the controls.

Fable. Was a sick story one of the only games with children.

Fable 2 is going to own
    Sexually transmitted dieases, and a pet dog
       Life doesnt get better than that.

Other then Morrowind
I would say the Dungeon Siege games,
Now if only Bethesda would add a MP choice to TES it would be perfect. Like DS II, let players decide weather to play mp or not.
