Re-arranging built-in/Blizzard/default AI build order steps, well, might be interesting/fun for a while, but it doesn’t make the built-in AI smarter/stronger, and it’s also not easy for every1 to modify,
If you want a REAL custom AI, but works only for SC 1.16, (But Bli 
ard will add it to SCR in the next 20 years, hopefully 
) there is BWAPI, BWAPI Revamped.
