I can't believe a mod like this was released this soon without the CK & it actually works. Although it's a tad bit buggy.. I'm currently hanging out in Solitude if you want to chat.. It doesn't appear you can PK/PVP anyone yet..
Here's a video, of an older version ~ www.youtube.com/watch?v=Opcvzmyg0lM ~
The older version consisted of all other players appearing as ghost horses.. It has been updated a bit so that other players now look like your character until the author of the mod can patch it to recognize everyone's individual character designs
