Interesting or Realistic Star Systems

It's a commercial program from NBOS Software: http://www.nbos.com/

It's sold through RPGNow & DriveThruRPG as well.

Good program with a moderate learning curve. Pretty memory & CPU hungry.

I remember using 'Heaven and Earth' for a lot of my stuff with worlds -- it gets into some really good layouts and mapping

I liked it with the info it uses from the 'World Tamers Handbook' .. so I reccomend H&E for anybody curious
