I loved Oblivion.
I loved Fallout 3.
I adore Morrowind.
That's the order I played them, Oblivion I put down to being my first time, a shame to get your cherry taken by such a rough edged brute but it lead me to better things, I really don't think I could play it again though, my final run of Fallout 3 is suffering too, I think it's over familiarity.
Morrowind on the other hand I've only played once and it utterly drew me in, as a game I think it kinda sucks, an imbalanced jumble of half baked systems...which is half the appeal, leaping to Solstheim and back, jumping again and landing in the middle of the Ghostfence to get slaughtered by Daedra and corprus infected, Skyrim isn't going to top that, it probably won't keep me up at night pondering the nature of godhood and immortality either.
I'm sure I'll love it though
Seems I'm their little bitch
