In relation to the new rating "18+", good marketing strategy, many potential customers won't feel embarrassed while buying a set and Lego has the perfect justification to charge even more money for big models. Hopefully, aside the increased depth of adults' wallets, there will also be a growth of mature themes or, at least, some serious revival of the classic ones.
Finally, after years, Afols are officially recognised, it is time to celebrate it with a new acronym, Official Adult Fans of Lego.
Long live the Oafols!
