Dragon Age - Play expansion before completing the game?

I just got the expansion pack dragons awakening. Should I complete the original game before moving on to this? If I was to play the expansion now, will it ruin my game in terms of spoilers etc.

I would suggest playing the Main Game first: that way, if you wind up with a character you really like, you can import him from any save into the expansion.

Ok cheers, I wouldn't usually even think of moving on to an expansion before completing the original...It's only because I am stuck and it's really annoying lol

Thanks for the info guys:)

I'll finish the original first before going on to the expansion. Wow! 70 hours lol... I am 25 hours in at the moment so I should have alot of play left which is good!
