As far as the werewolves go, it's not like they were devoid of substance, though. With the likes of Sinding and the Circle, we got the opportunity to see more of the relationship between Hircine and werewolves (they don't all turn into gibbering idiots, and werewolves are destined to go to The Hunting Grounds on death). We learn that werewolves can die of age. The totems provide new interesting information, too. Even the word walls provide subtle info:
Not only do we get definitive proof that werewolves form packs, we get the name of one such pack and one of their past leaders (who was also a female, showing male werewolves aren't necessarily dominant). We also get the name of someone else who was able to best Hircine in his Great Hunt.
Yes, seems Bethesda is going back to the Daggerfall days with transforming at will and wolf packs(We had a single daggerfall quest where werewolf was in a pack). And can werewolves die of age, or do they simply take longer to die? Albjorn says something that sparked some interest. "You are more than mortal. You are Moon-born. You are wolf."
Then again, it could mean something different. And I guess Bethesda just wanted werewolves for the Companions questline and nowhere else. "So, you're a companion then? I can't imagine you got your gift anywhere else."-Arbjorn on player's Lycanthropy. That is some interesting information, as well. I love that Bethesda did flesh out some Lycanthropic lore. I remember in Bloodmoon there was an ability called "Spirit of the Wolf" ever since I imagined werewolves to be tied with something more primal, comparing to indians and native barbarians and such. I guess "The Totems of Hircine" book gave much info on that, saying werewolves where around before men could speak or write. Sort of like the Cavemen era of our world. The whole thing even says it was before Tamriel was civilized.
