Varieties of Faith in the Empire (the book as seen in Morrowind) indicates that there are a number of pantheons in Skyrim, including Alduin, Dibella, Orkey, Tsun, Mara, Stuhn, Kyne, Jhunal, Shor, Ysmir, Herma-Mora, Maloch. Will these be included in the game, or more to the point, should they be included in the game? And will they form huge structures (much like ancient Greek pantheons)?
Reading the Skyrim Lore page on UESP, the religious aspect in Skyrim, seems pretty interesting and may be a dominant feature of their culture which means, at least to me, that it should be in gameplay.
