sidenote:
if not the private servers then maybe the personal build servers all the way back from 2011 (context: they were much like modern team create on studio but you did it on the normal roblox, and you had a "stamper tool" where you could edit a blank baseplate and create with your friends. now you could control who entered and left, using "whitelisted" (you type in the usernames of users allowed, wether friends or not), "friends only" and "public". there was an automatic save file that saved whatever the heck you built.).
tell me if you have any thoughts about this (please construct on your answer)
