I've played through Oblivion, and recently started on Morrowind. One thing that strikes me is that the Beast races are far too much alike Men and Mer, in my opinion. Although it's probably easier for the animators to have similar animations for all the races; seeing my Argonian run on all fours would be magnificent!
This should of course apply to Khajit as well.
So, the topic of the discussion: running on all fours and more beastly attributes... Yay or nay?
(I'd love to see more Beast races by the way)
