I don't think I've done the Fade more than once after my very first playthrough back in the day. I've used the mod ever since so much so that I barely even remember what I hated about it lol. I just know I hated it.
(tho there was this one graphical glitch that really made me sick to the stomach)
On my first playthrough I first completed Orzammar and I was complaining how I hated these damn Deep Roads! Little did I know what was awaiting me in the Fade 
Soo... I have actually done the "replaying" part this August, because I wanted to get this over with and go straight into work after the holiday was over... But at times my resolve reminds me of a pudding
Now that you have mentioned this, I think I'm going to replay the games again. Probably, I'll start playing as a male Warden (I have never done this, but I'm going to make one of the worldstates in the Keep with male Warden anyway, so why not try it out?). I think, he'll be a Cousland or Mahariel, romancing Morrigan. He'll make the same boring good choices I always make (except Connor case - I'm so lazy to go to the Tower to save everyone, so I usually kill either Connor or Isolde), perform DR and go on his merry way.
Then I'll create another female mage Hawke (same old bore) and I'll try something I was thinking about for some time which I can't explain other way than by making an example. E.g. to get friendship points with Fenris you need to take a lot of pro-Chantry/pro-Templar/anti-Blood-magic choices. I want to try and get as much frinedship points with him while not doing this and being very pro-mage - by not taking him on specific quests or making "neutral" choices. Or rival Aveline while still being very diplomatic and law-abiding. Or befriend Merrill, while.... Nope, I don't think I'll ever be able to do this. I doubt it's possible to get companions bars full this way, but I'm gonna plan and play!
I really like self-imposed challenges.
So yes, I'm going to replay the games. I think I'll finish DA:II by the time the Keep goes into open beta.
