According to the Japanese developer, this is due to the fact that in his youth, games were a niche entertainment and not part of mass culture. In the 80s and 90s, the industry primarily attracted people looking for an alternative to a traditional career. Taro considers himself to be part of this special and closed group of "outcasts" who found refuge there.
Now the situation has changed: young developers have grown up in a world where games are a normal, popular and profitable business. This naturally attracts people of a different profile.
The creator of NieR: Automata noted that the new generation of designers is more "normal" and socially adapted. Although the industry has become more professional, many veterans nostalgically remember the old, crazy times.
