Three floors at Fort Drakon, including the archdemon. Over 110 hours of gameplay, which given the forty or so bucks I paid for it suggests that I got a pretty respectable ROI. I’m nowhere near a hardcore computer gamer, so I probably wasted a good 30 or so of those hours doing stupid or redundant things; but it was worth it.
If you have the time, pick up Dragon Age: Origins: it’s the business. Hell, my wife wants to play it when I’m done, and she doesn’t play video games.
