not only because it doesn't look THAT good
Some features, like spawn map, were implemented in a more useful, albeit less pretty way in RMod than in XR.
thoroughly clean up a very convoluted script
This, however, is a real problem. RMod code is a mess to say the least, I actuallly tried to clean up, but ended up just ripping media (images of HP bars, etc) and ideas and implementing whatever I liked anew by myself. It was easier than cleaning up RMod.
And before you ask, my mod is for my own use only. It lacks any GUI settings and is hardcoded to suit my playstyle.
