i WOULD if they ever released them for ps3. but of you are asking about quality, they typically make some real good expansions.
I have been wanting to get back into it for a while, but IMO it takes multiple hours in a row of playing Skyrim for me to actually put the disc in. Usually I'll hop on and play some Madden or FIFA. I'll probably wait until Christmas time to play Skyrim more... and I'll definitely get that expansion.
