The more imaginative creatures there are in the game, the better.
Fiction opens the door to creativity, but so many authors/movie-makers/etc don't bother walking through that door and instead use tropes. Which is dull.
Examples of more imaginative creature designs include Morrowind and Shivering Isles.
Perhaps it's strategic marketing to make a game which follows the creature roster of "The Hobbit", I don't know if that's Bethesda's intention (I suspect it is.) But I'd much prefer that they forged new ground in this area, as they had done with some of their other titles.
I still would like to see a couple to recognize.
Heres some.
Red Tailed Roins - Monkey ith red faces and tails. They use there threatening red face to scare off bigger predators and use their tails as bait to catch unsuspecting small prey. The rest of their body is covered in a tan fluffy coat. Theres a myth if you ever flip a septim into the air and a roin catches it, it grants you good luck for 6 years, if it throws it back at you you gain 14 years of bad luck.-And they tend to throw them back/ Quite the gamble. - Native to Elyswer.
Yaenik - A crocodile like beast found in Skyrim. It makes ts home at the botom of ice covered lakes waiting for unsuspecting adventurers and prey to try the frozen lake bed as a short cut. It then uses its jaws to grab the victim and submerge under the ice where it waits with its massive jaws either crush the victim to death or have it drown or die of hypothermia. It has small spear point like snout with prongs used to jagg open the ice surface. It is also covered in scaggly fur and scales. It may seem reptilian but it is warm blooded. It also has a gas bladder where it stores methane gas from its digested food to act as a heat regulator. If you were to hit the Yaenik in the lower abdomen with some sort of heated spear or weapon it would explode or the gases would react and cause a eruption of gas of stench or possible explosion.
