I have DA2 preordered and am currently playing through DA:O and finding it pretty entertaining. I see that Awakining is 50% off on Live right now, is it a good expansion?

I'm wondering this too, saw it cheap on PC and I'm considering it

It's alright. At that price I think it's definitely worth it - my own review of 3 stars was mostly aimed at the exuberant price, at around £32, on consoles.

Very good for that price. I got it full price and still had a lot of fun with it, so at half the price I would say it's  no brainer, especially if you like Dragon Age Origins.

I bought the game on Steam, but I haven't played it yet. Here are the reviews on Amazon. Most seem to think it's good, but not worth the launch price of $40. The reviews lead me to believe that, while it has some problems, it's easily worth $15. 

I thought it was great. The ending didn't happen too quick which I thought was brilliant.

I saw this for 20 quid with Dragon Age: Origins on the 360. Should I pass up on this and miss out on the game? (My PC is crap).

$15's a good price for it if you're starved for DAO content, yea.

I bought it for 30, if you loved Dragon Age you will love this.
Pretty long too.

I played the PC version.  I preferred it to the OC by quite a bit.

Yeah, but be warned, it's a bit too easy.

It's definitely worth it, like others said it's a bit easy but they added some new gameplay mechanics and if you love stat manipulation and tweaking, there is some great content.  The story is way more focused than the original game, which I thought was more about collecting party members than actually solving the issue at hand, the bad guy is pretty awesome and there are NO stages that I loathe like that horrendous Fade stage and the never ending dwarf dungeon that will always keep me from replaying Origins again.
 
It is super easy though.  That's one thing that kinda blows.  There is no level scaling and it's like Bio-Ware assumed that everyone who beat Origins did it at level 15 or rather than the 20s.  Still, at $15 is a great piece of content.  How GB seemed to totally forget about it when it came time to award best DLC is mind boggling to me, especially when they said something like, this was the year story driven DLC really came into its own.

The thing that threw me off was how it incorporates your character from the main game. It felt clunky, especially considering the ending I chose.

Eh, for 15 bucks, maybe.  I didn't care for it much.  It provides new characters and give you little reason to care about them (not that it did it all that well in the first game) and there is a severe lack of carry over from the initial game in terms of your decisions (no surprise there).  On the other hand, general gameplay is still fun.

Do you have to have finished Dragon Age if you want to import your character?

So far I'm pleased with it (just started playing it the other day).  I think for some reason I kept thinking because it was DLC it would be over far too quickly.  But after a few hours I feel like I've barely touched it yet.

i grabbed the ultimate edition for 40 bucks off newegg i think -- definitely worth it. 15 on it's own? don't think so, but it's a very well done piece of dlc
