SWTOR should probably go on that list, as much as I've played it. I just finished my 6th character arc (bounty hunter) and started the last two, sith warrior and sith inquisitor, this week.
Unfortunately (so far) my fear for that game has come to fruition, as they've added absolutely nothing to it story-wise in the year since release, with the exception of the quest for HK-51, which can be done in a day. Everything they're added has been raiding and PvP (well, and cartel market). Which was just adding more grinding to an endgame that was already nothing but grinding.
And I've actually done a fair bit of it, mainly dailies, space missions (they introduced new ones a month ago that have black hole comm rewards) and hard mode fps. I still haven't done any raiding yet.
The story part of it has been great for me. Playing through all the class stories, I'm online as much now as I was a year ago (which is bad, really...). I don't know how the expansion's going to be. I worry that it's going to be less than a week of new stuff and then back to the endgame grind. They've already announced there's no class story aspect to it, and everybody's chapter 4 is a faction-wide story arc, which is a disappointment, if not a surprise. There's enough to keep my sub going for another 6 months, but after that? Not sure.
Anyway, I got sidetracked, the main point was that I'm okay with a certain amount of grinding, too. There's a calming aspect to turning your brain off like that. But I don't know that Bethesda can give me enough interesting stuff outside of that to keep me invested.
