Vegas was a blackmail city for mafia alphas to blackmail high status men using women and gambling, the high status men got there through real communications with humans and high T work environments. Gacha is just extraction of wealth from rich lonely low T guys that avoid verbal conflict with other humans, the rich guys these days are mostly in tech which is a low T low conflict environment. Instead of real human prostitutes to satisfy high T high status men gacha uses virtual anime girls that are ideal for soft guys. China is genius in art of war.
