Only adding more planet types, so I guess if it works with Diplomacy it'll work with Rebellion?
No, the planet entity files will need some additions...
The Vasari's Stripped to the Core destroys the planet and turns it into a dead asteroid or asteroid belt...there is a whole "ruinDef" section that defines the effect to be used, the planet to convert it to, the amount of resources to be earned, etc...
You could right a script to add the lines in...or you could just copy the group of lines from planet file to planet file and change as necessary...
There may be some other lines added in the entity but I can't think of them...
Also, I think some of the mesh files need an additional line, but that line is like the first one in the mesh file or something...script could add it in easily I'd think....
