So I played through Dragon Age Origins a little after it came out and loved it. However since then I had to reinstall windows at one point and lost my save data, should I replay Origins in preparation for 2?

Well I played Dragon Age on 360 when it came out
 
But then I got a better computer and about a couple of weeks ago I started playing it on PC with all the DLC in preperation for DA2, also I felt like I hadn't done as much as I wanted to in my first playthrough
 
So I recommend it

It isn't necessary, but you should.

Definitely. I would recommend it even if there weren't a sequel ready to come out.

i have never played the first, but enjoyed the demo for the 2nd. I may go pick it up today.

Only if you actually want to play it.
It's a long ass game, I don't recomend doing it if it's just for the save import.

However I am personally replaying it right now since i had a second half finished game from some time ago anyway.

I thought about this but then I remember the Fade level and I decide against it.  I've already beaten the game twice though, plus I can't ever see myself playing as anything other than an Arcane Warrior so there wouldn't be much for me to do different.

Man, losing save data sucks, especially on a long assed game like this. 

Having lost your save, I can appreciate why you would want to play through again.  I did, though only because I was only willing to buy awakening once it was discounted.  I personally found the game just as fun but I basically skipped all the dialogue.

Theres never too much room for some dragon age, never stop playing.  EVER. I still play KotOR.

After playing the demo a couple times through I decided to start playing Origins again.  I had one save game near the end and another in the middle-ish.. so I started a new playthrough. 
 
@Tennmuerti: Great mod!

You should play it through because its awesome, still is.
 
So yeah, go play.

yes I did

Oh man, it comes out in 10 days and Im still on the grey warden beginnings on Origins- I WANT MY SAVE! 
 
WILL I MAKE THIS IN TIME, GIANTBOMB?!

@Chaossebba Easily.

I played through DAO when it came out on a warrior, still have the save but no idea what decisions I made. I started a new game (rogue) a few days ago and im making good progress. 

Also, im I the only one who likes the fade level ? Its easy and different.

well  I finally decided that im going to pick up the 1st dragonage that comes bundles with the exp pack first and then dip into dragon age 2, i hope this is the right decision. :S

Exactly what I'm doing. Origins + Awakening + Witch Hunt run before DA2's release. 
 
So far: finished Origins, started Awakening, then jumping onto Witch Hunt.
