Based on survey data from research firm GEM Partners targeting a total of 180,000 people. The "Oshikatsu MAP" compiled by the survey reveals the gender ratio and average age for each entertainment genre.
The survey data covers all forms of entertainment, but below we'll focus on games only.

The game with the youngest average age, and the only one with an average age in their teens, is Supercell's "Brawl Stars."
IP with game apps for smartphones has a relatively young average age, with many titles featuring people in their 20s.
On the other hand, IP focused on home game consoles has a higher average age , while titles with a long history seem to be mostly made up of people in their 30s and 40s.
The average age of users of both Final Fantasy and Dragon Quest is in their early 40s. Although FF and Dragon Quest are also available on mobile devices, the average age is still high.
By genre, sports and shooter games have a significantly lower average age. PvP games tend to have more young players . Additionally, the majority of users of PvP and sports games are male.
Interestingly, shooters not only have a similar age mix, but also a similar gender mix : Valorant, Fortnite, and Apex all have a similar ratio of around 85:15.
Whether by coincidence or fate, "Pokemon" and "Fate" are completely different in terms of starting point and subsequent development, but they seem to be very similar in two areas: average age and male-female ratio.
miHoYo, known for Genshin Impact and the Honkai Impact series, mainly produces games that can be played on smartphones, so in addition to the low average age, it is also notable that there is not a significant bias in the gender ratio.
