You know how most dragons have six lims? You know, four legs and the wings? Well, I wonder what the point was with the dragons in Skyrim having only four limbs, their hind legs and wings. Most dragons I see have four.
But whatever. They will make how they make it. But honestly, this is awesome.
I imagine they wanted it too look more realistic, as realistic as a dragon can be. Birds only have four limbs and they are our fliers, so I'm guessing they based their dragons off some birdish qualities.
Well, I did often think of dragons possibly relating more to birds than other lizards. It sort of reminds me of some kind of animal I saw a video about that has been long extinct. It looked like it was related to crocodiles and whatever, but it's actual descendants were whales.
