DA lore is great. So is TES lore. I find it difficult to compare the two because I think they are done in two different ways. DA lore is more fluid and straightforward and easier to "study", so to speak. TES lore is twisted and organic and you don't really know what's right and what's wrong. Both are really good in their own right.

TES is really good for giving you a world to run around in and roleplay whatever you want.
