Empire and XConq are basically the same, but the last one it's written in TCL/Tk+C and expanded a lot. Sadly isn't maintained very well today, as I found bugs

Empire and XConq are basically the same, but the last one it's written in TCL/Tk+C and expanded a lot. Sadly isn't maintained very well today, as I found bugs on restoring a save file made from the last GitHub build. And it's a pity because anyone who liked VMS Empire would love XConq in the spot.
