Pokémon, Legend of Zelda, and Smash Bros all sell consoles and their innovation is child-targeted so they innovate in weird ways cuz kids don’t care really about processor speed or graphics cores.
In my experience, at Pokemon release events in Japan and in the United States, the majority of attendees lining up are adults, most under 30.
Planting the seed early and reaping rewards for the entire life is definitely what works for them.
