So I tried it out last night. Took about 10 minutes to generate an 8k x 8k map. It is really simple to do. You just go to the map generator and now it creates the world instead of just a map preview. It was a little buggy. Once the map was generated I couldn't exit and had to close the game. But then I logged back on and my new world was listed next to Navezgane as an optional world to play in. Can't remember the random county name it was given. Kinyajuu has mentioned he is still doing final touches. I started a new game in that new world and it loaded up as fast as Navezgane does. Very nice. Now that it is created I can keep creating new saves in that world and it will load up quickly each time.
