I like some of these maps, but I can't put them in my mod with a good conscience knowing that what I'm doing is just as bad as taking MAP01 out of TNT, converting it to Chex, and calling it mine.
I occasionally try to make a map that has a similar feeling to another map (like Villa Duel / SSL2 or Consilium/Uroborous) but they are drawn from scratch, and are always my own interpretation, my attempt at taking what I like of the original and making it better.
These maps were made by Team TNT; even though QG was able to get permission to use their music, taking their maps is going too far, and I doubt they would even agree to the idea.
