Thanks for bringing this to OG.
Here is my old reply to that former thread on AG:
Holy sh!t, there is even original prototype source code for "the soul of the sims" by Will Wright in
"117503320-The-Sims-The-Soul-of-the-Sims".
Lots of screenshots and infos on the editor "Edith" here :
"117493169-The-Sims-The-Sims-Pie-Menus-Video-Demo-Transcript"
The "Editor" (Edith) was leaked as DLL back then and even got cracked :
There was Edith, Ingred and Freshness.
