I am also spreading the word. My experience is that young teenagers like my son, prefer "action" gaming. I guess Prospectors is too boring for them. Older people as my friends still struggle with the entry barrier of account creation, scatter, etc. I have not tried steem monsters myself.
Maybe when Voice comes out and account creation is free it will lower the entry barrier for the mass market to start adoption.
To me, it is fascinating to specially observe the token economy of Prospectors as time goes by. I can't wait to see the first plots to expire to witness the market reaction to that.
