In dungeons they are spread into 2 kinds of groups you will encounter:
Draughr/Bandits
or
Falmer/Automatons
While on the above land there are:
Dragons
Bandits, bandits everywhere
Giants/Mamoths
Bears/Sabre-tooth cats
With the small variation of rare mobs like vampires and hagravens and trolls. Personally I like the rare encounters with these creatures, but I cant help but yearn for more types of creatures...especially with such an expansive map. What do you think?
