I am also planning on making Manaan in the near future. It would be fairly simple to make, and as a starting project it would do nicely. Since Korriban and Taris have already been taken.
Upon the completion of my Ebon Hawk, I was invited by a few friends to remake KotOR entirely in Minecraft. ***WARNING! READ MAP CHANGELOGS BELOW BEFORE DOWNLOADING A MAP VARIANT*** While it's been 3 years since you've last heard from me, this project will be finished, so do not give up hope. While this is disheartening, I assure you it is only a minor setback.
I recently reinstalled Windows and lost my most up-to-date version of the map, therefore I have to work with the current version that is available for download.
There is a bit of unfortunate news though. I am back! It's been 3 years since I last touched this game, and coming back to see this thread has motivated me to complete this build and make sure your support has not been wasted!
