I just picked up The Witcher 2 somewhat recently (thanks to suggestions from people here, and the fact that got it for $20 (non-EE) and got said EE upgrade for free), and I have got to say... even after only recently finishing the tutorial and making a brief foray into Chapter 1 thus far, I am really, really enjoying this.
For this type of game, a really good story makes it that much better on its own (I've got other titles if I want mindless entertainment), and I must say, on my first play through, I am already attempting to figure out second and third-order effects of choices.
If I enjoy it enough, it might also be the first game I ever even think about playing again and actual mean to finish up.
With the promise of missing possibly hours of content throughout the game due to choices made, I really want to play different roles for this game. [I have said that before for other games and it never happened, so... we'll see.

But the combat, for an RPG, I've really enjoyed, and it's super early in the game.
