In morrowind you catch the disease, in fact I think in every elder scrolls game there was the disease. And i meant walking on all fours not sprinting, its as though the werewolf would be stalking prey. ANd wolves actually fight for you while in beast form.
Walking on all fours at all times would make it into twilight wolves in my opinion.
A werewolf is half man, half wolf amalgamation.
When I think of a werewolf/Lycan I see the underworld movie version, or the wolfman movie version and actually how they look in Skyrim.
I love the running on all fours cause it is naturally faster, but standing other wise and attacking, I don't want to play a WOLF, but a WEREwolf.
I hope the transform at will be included in the mod.
