[pathfinder]

When I want a ringworld or sphereworld I usually generate a random universe then change one of the worlds to ring/sphere. to make it a starting point (or any others) there is a button at top left called"starting points). The drop down has a list of numbers. The numbers correspond to the number of the race as you make them in creating the game.

Hope this helps.


Not sure about the other items as I haven't made many maps...
