Err make your own one if you think Akatosh Mount was rubbish, unfinished yes but definitely not rubbish, Saiden Storm tutoreals help other modders create completely new creatures.
Even developer admit thats was awesome mod

Well I never personally tried it for very long because my Oblivion always crashes on my computer, so I probably missed the updates and all. The effort was great but it's not like they could fully implement a whole new feature into the game that was not there at all to begin with, so naturally it couldn't have been absolutely up to standard with the game. I just mean that now dragons are a big part of the game modders can make something that's beyond the standard of the original game, instead of having to make do and make something a little substandard because they basically have to start from scratch.
