I was watching a buddy of mine play this a couple nights ago. It looked like it was a ton of fun to me.
I'm going to pick it up as soon as I get a 360.
With that being said, it's a excellent game. Visually amazing, with a great plot with a few different outcomes depending on your choices. Rememberable characters are a big part of this game as well (A golem with a hatred for birds, so he steps on every one he see's? That's genius!), and lots of customizable classes, skills, and talent builds.
I bought it, still play it every once in awhile even though I beat it a few times. Don't regret it a bit.
I have yet to check this out. I saw it being played on a PS3 for maybe 10 minutes, and it looked amazing. Bioware has never disappointed before so I am sure I will love it whenever I get my hands on it. Although by that time I will most likely be too into Diablo III to spend much time.
