I might consider coming back to Roblox, I have a factory place that I never got fully functional (I also don't know how to script so I paid people tickets/robux to do a lot of it for me).
I would like to get it running right and polish it by myself, may be a bit difficult considering I still can't script but I can fully understand lua so I'm sure I can manage to get it to work if i keep at it.
It's odd, it's like being able to read a language but not able to actually write it ;_;
