So far, Skyrim has about 20 confirmed creatures (Draughr, Skeletons, Trolls, Giants, Ice Wraiths, Giant Spiders, Dragons, Wolves, Horses, Elk, Mammoths, Saber-Toothed Tigers, Centurion Spheres, Dogs, Skeevers, Bears, Rabbits, Horkers, Dragon Priests and Ice Atronachs).
How many more do you think we'll get? I'm sure we'll see the other 2 main atronachs, and some of the series staples (mudcrabs, scamps, etc) wouldn't surprise me, but Bethesda seems to be taking a quality-over-quantity approach in this game. They've emphasized that they want creatures to look and behave like they're truly a part of the world, which might mean more realistic creatures, but fewer overall than OB or MW.
So what do you guys think? I personally feel like I'd get bored quickly if creatures were less varied than in Oblivion, especially after hitting the 100 hour mark. Will Bethesda go above and beyond and give us a large variety of well-crafted beasts?
