I am a useful, researcher and sharing person in this game. Since 2015 I shared my created rooms with my friends, but I don't have to share every topic or structure, The subject you are talking about is a subject that belongs to me. and a one-month study emerged as a result of the research.
for example : I build Titanic Room, I have 8 months of labor and falls into the same category as the subject you are talking about, but I do not have to share my long work and effort with everyone....
Do you think I'm useless? watch this video series.
