The only MAJOR Lore contributon (in book form) to Oblivion was the Warp in the West, I just want to see some lore intensive books. Morrowinds books (imo) had much more substance than Oblivions, whereas Oblivions were all anecdotes, not lore related.
No. Just no. I suppose someone doesn't know as much as they could about the Ayleids (which were barely explored in any way before Oblivion), the Tamrielic invasion of Akavir (no, I didn't accidentally switch the two continents), Reman Cyrodiil, Pelinal Whitestrake, the procedure (in detail) involved with opening an Oblivion gate, the various vampires of Tamriel, two important figures in Skingrad's and Bravil's history, and Sancre Tor, among various other things. Either you have some reading to do or your sense of lore is strange. I'm pretty sure Morrowind had many anecdotes and I know Daggerfall had many, as well. If you're unwilling to count those, then there are many to cut from all three of those core games. Talos forbid we get to enjoy amusing stories or reading material such as Daggerfall's book of jokes, its entire King Edward or Real Barenziah series, the tale of light and dark from Daggerfall (detailing a grandfather's anecdote as dictated to his grandchildren), the book on Nymphs in Daggerfall, the book on faeries, in Daggerfall, the rude song and less rude songs, Morrowind's scrib-related children's tale, Morrowind's poem book, the Sermons of Vivec (all 36, which I have counted as individual books), Morrowind's Dance in the Fire series, and many other from both games. I mean, Wabbajack from Daggerfall was definitely an anecdote.
