I first played it on PC a year ago, and CD Projekt was nice enough to patch it with all of the Enhanced Edition content (though it's still pretty much identical to what it was a year ago, except there's more content).
Graphics: It looks fantastic on PC, but it's a port to 360 so you can't expect that.
Difficulty: It gets a great deal easier. The difficulty curve is one of the game's biggest problems, and it was worse back when there was no tutorial. Evade a lot. Never block. Steel sword for humans. Use Quen like your life depends upon it (because it does). Don't be ashamed of going down to Easy for some parts.
Story: The storyline is fantastic, though Geralt has no personality whatsoever.
Sound: Again, everyone except Geralt is fantastic.
I'm enjoying getting back into it, but at the same time, I am having to replay the dull trudging parts at the beginning of the game before it really hits its stride in Act Two.
