If this game is going to be made using the Skyrim engine, does that mean things like jump attacks from Morrowind will not be possible? As it stands in Skyrim jump attacks are not possible. Additionally I'm assuming the slash/stab/overhead mechanics will also not be there?
Thank you for answer this rather simple (and probably stupid) question.

From what I know, Skywind is
From what I know, Skywind is an incredible creation but down to it's core it's essentially just a Colossal Content mod even though at times it probably won't feel like it due to it's immense scale so therefor I don't believe such things would be added, however there is a mod currently in a WIP stage that is making it possible to do what you ask and it is going to be a modder's recourse when it is complete so who knows? maybe those who are working on Skywind will incoporate said mod into it
Here is the Link to it.
