Yeah, any playtime stat is going to skew wildly towards children and maybe young teens, who will play whatever's inexpensive on whatever device is available. That doesn't mean Spider-Man 2, that means Roblox and Minecraft.

In turn: League of Legends, famously, runs on pretty much any computer made in the last decade, and is built for long play sessions. A gacha like like Honkai Star Rail is not, their play sessions are designed to be comparatively short. HSR still brought in over 100 mil in March, though, and that won't be reflected by this particular metric.
