This is just more nostalgic bullshit separated from reality. The gaming industry is larger than ever, resulting in more bad games, but also more great ones. The 90s were not some grand time period with perfect games. They were limited by technology, understandably, and could never be as deep as modern games.
You happen to be a person who enjoys simplicity, and that's fine. But what you desire is something unlikely to attract attention for large investments. Instead maybe you should try more mobile apps.
edit: I'm making a few assumptions here, but they seem fair based on your statements. Have you even played Witcher 3? And you still think games from this era aren't fun? I guess I just don't understand what you fundamentally would like to see changed. There are plenty of games without massive grinds (virtually all single-player RPGs lack grinding).
