Skywind, as you might imagine from the name, is an unofficial community mod that aims to recreate the entirety of TES: Morrowind within the much superior (and prettier) Skyrim engine. While I would usually express some serious doubt about the mod ever coming to fruition, the team behind it has put in a colossal amount of effort and the results speak for themselves.

If you don't believe me, check out the recently posted "Prevelance" trailer that showcases the team's progress with Skywind so far. There's giant mushrooms, well designed pieces of armor, strange Elven architecture, and most impressively, entire cities built from scratch.

Keep in mind, however, that everything shown here is "but a small fraction of work done on Skywind over last few months. Music, voice acting, sound effects, quest implementation, bug fixes, etc. couldn't be shown properly in this video, but are being developed along side the visual progress. All footage shown is from the private developer alpha and is subject to change".

If you're interested in learning more about Skywind, and potentially getting involved in its development yourself, head over to the official website. On the other hand, if you're looking for a playable version of Skywind that you can mess around with I'm afraid you're out of luck as its still so early in alpha that the team is not comfortable releasing it to the public just yet.
