Hi!

I want to change the stat of ships and structures to suit my own taste. How? Is there an editor for Supremacy?

Thanks a lot!

PS: Supremacy is a really good game! Keep it going!

The May update changed a few things, and the editor no longer works with it. Hopefully the next update will have a working editor.
Meanwhile, try editing the files by hand (edit the source code of the XMLs). Most stuff should not break the game.
You can also change some of the galaxy definitions in some text files, namely UniverseTables.txt.

I figured out that I can edit xmls via using the Excel. It is not enough. How I can edit those xmls FULLY? In addition, I can't find xmls related to structures and ships. Where?

Thank you so much!

Use notepad++, it's great for XML editing.
