I wish to disagree.
While I haven't finished the game, (I will someday, honest) the game really reminds me of the good old dungeon crawlers, like Ultima Underworld. Sure, the controls are a bit hard to get at first and the plot is a cliché, but you actually have to do stuff to progress. And it doesn't hold your hand and tell you exactly what you have to do, just gives you hints and lets you figure it out.
And there is actually difficulty. If you just go wandering around the place after you complete the tutorial and stick your nose in a place where it's not welcome, chances are it'll be sliced clean off (Oh god the liches). Unlike in Oblivion where you can complete the main quest at level 1.
It's not perfect, obviously. The thing that annoys me the most is that you can't tell exactly how hungry your character is, meaning that you just stuff a little food into his mouth, wait a few minutes, and then he says he's hungry again.
If you played games like Ultima Underworld, I'd suggest giving it a go.
