I lost interest in the game well before completing it, but after playing a hundred hours. Especially with some of the Steam mods -- nutrition and temperature ones, in particular -- it's a pretty entertaining and pleasant experience, often surprisingly restful. If you've gotten out of the habit of hiking, but used to enjoy it, you might find it worth playing.
You won't get interesting conversations or memorable characters anywhere in the game -- this is just Bethesda, not Bioware or old-school Square -- but if it's on sale, and if you haven't played one or more of the other _Elder Scrolls_ games to exhaustion, it's probably worth it.
(And to balance out my ambivalence and doubt above, let me say that I'm almost certainly going to buy _TES5: Summerset Isle_ on launch day, and I continue to hope that they'll eventually set a game in Khajiitistan.)
